SYNTHESIS PROCESS OF NON-ZEOLITIC MOLECULAR SIEVES

Abstract: Non-zeolitic molecular sieves are prepared by contacting a body of alumina or silica-alumina (optionally containing reactive sources of phosphorus pentoxide and/or other elements desired in the non-zeolitic molecular sieve) with a liquid reaction mixture containing a reactive source of phosphorus pentoxide (and optionally reactive sources of silica and/or other elements desired in the non-zeolitic molecular sieve), and an organic templating agent, thereby causing the body to react with the liquid reaction mixture and to form crystals of the non-zeolitic molecular sieve within the body.

Description: This invention relates to a process for the production of molecular sieves. More specifically, this invention relates to a process for the production of non-zeolitic molecular sieves from alumina or silica-alumina bodies. Background of the Invention Molecular sieves of the crystalline alumino-silicate zeolite type are well known in the art and now comprise over 150 species of both naturally occurring and synthetic compositions. In general the crystalline zeolites are formed from corner-sharing AlO₂ and SiO₂ tetrahedra and are characterized by having pore openings of uniform dimensions, having a significant ion-exchange capacity and being capable of reversibly desorbing an adsorbed phase which is dispersed throughout the internal voids of the crystal without displacing any atoms which make up the framework crystal structure. The early procedures for synthesizing zeolites produced materials that were very fine, often less than a few micrometers in size. Such small particle size powders are difficult to use in many industrial processes. Furthermore the small sizes can also create dust hazards for people who handle the materials. Larger zeolite particles, having average particle sizes of the order of 10 micrometers upwards, are preferred for many applications. However, for such large particle zeolites to be useful in all processes in which zeolites are used industrially, the large particle zeolites must retain the ion-exchange properties, adsorption capacity and selectivity, thermal stability and catalytic activity of finely divided crystalline zeolites. In addition, the large zeolite particles should exhibit high attrition resistance and crush strength. Although larger zeolite bodies having sizes in excess of approximately five micrometers can be prepared by agglomerating small crystals, a typical agglomeration process requires a suitable binder, such as a clay, silica or alumina gel, or inorganic or organic adhesive, and processing conditions that assure reproducibility of the properties of the agglomerates. Because such processing conditions are often complex and difficult to control and because the binder material, which is a relatively inert material relatively incapable of adsorption, tends to reduce and/or modify the adsorptive and catalytic properties of the zeolite by dilution and in other ways, this approach is not optimal. Accordingly, processes have been developed for producing zeolites having relatively large particle sizes ranging from tens of micrometers up to several millimeters or more. Many such processes begin with the preparation of a precursor, or preformed body, which contains certain reactive or unreactive kaolin-type clays and which can be converted by chemical means to a zeolite body that retains the shape of the preformed body. Earlier preform-type products required expensive multiple synthesis steps, such as 1) admixing synthesized zeolite with kaolin clay and firing the composite to make it reactive, then further synthesizing additional zeolite from the reactive clay component by caustic treatment, or 2) bonding synthesized zeolite with silica sol, gelling, and further treating the composite with sodium aluminate at elevated pH to form additional zeolite (see German Patent No. 1,165,562 to Bayer). Cumbersome processes using sodium aluminate gel and water-immiscible hydrocarbon liquids have also been employed (see U.S. Patent No. 3,094,383 assigned to Engelhard Corporation). U.S. Patent No. 2,992,068 describes a method of preparing zeolite A bodies from preformed bodies containing calcined kaolin clay, caustic and optionally added silica or alumina. U.S. Patent No. 3,065,054 describes a preparation of zeolite bodies from pre-formed bodies containing uncalcined kaolin clay, caustic and a porosity inducing agent. U.S. Patent No. 3,119,659 describes a method of preparing zeolite bodies from preformed bodies containing either calcined or uncalcined kaolin clay, or both, caustic and optionally added silica or alumina. The preformed bodies may also contain added zeolite powder. U.S. Patent No. 3,119,660 describes a method of preparing zeolite bodies from preformed bodies containing either calcined or uncalcined kaolin clay, or both, and optionally added silica or alumina. The preformed bodies may also contain included zeolite powder and diluents . U.S. Patents Nos. 3,367,886 and 3,367,887 describe methods of preparing zeolite bodies from preformed bodies containing zeolite powder, calcined and uncalcined kaolin clay and sodium hydroxide. U.S. Patent No. 3,370,917 describes a method of preparing Zeolite Z-12 bodies from preformed bodies containing calcined kaolin-type clay and sodium hydroxide in an Na₂O : SiO₂ molar ratio of about 0.13. U.S. Patent No. 3,450,645 describes the preparation of zeolite bodies by extruding into pellets a mixture containing calcined and uncalcined kaolin-type clay, water and sodium hydroxide, aging and then ammonium-exchanging the pellets and finally digesting them in oil at 200°F (approximately 93°C). U.S. Patents Nos. 3,777,006 and 4,235,753 describe methods of preparing zeolite bodies from preformed bodies containing meta-kaolin and optionally caustic by treating those bodies with silicate solutions containing nucleation centers. U.S. Patent No. 3,909,076 describes the preparation of Zeolite X bodies from preformed bodies containing particles of both Zeolite X and meta-kaolin clay. The particles are stated to have an average size of from about 0.1 to about 50 micrometers, preferably from 0.5 to 10 micrometers. U.S. Patents 4,424,144 and 4,058,856 generally describe preparations of zeolite bodies from preformed bodies containing zeolite powder, meta-kaolin and sodium hydroxide. However, the zeolite bodies prepared by these and similar methods frequently, and often unpredictably, exhibit poor crush strength and/or adsorption properties. In addition, the wet strength of the preformed bodies made by prior art methods is generally quite low; the preformed bodies that are converted to zeolite often disintegrate during aging and digestion, especially if any agitation is used. In addition, the rates of zeolite formation are generally slow; many of the examples in the prior art require three days or more reaction time. There have recently been reported several classes of microporous compositions which are not zeolitic, and which will collectively be referred to hereinafter as "non-zeolitic molecular sieves", which term will be more precisely defined hereinafter. These non-zeolitic molecular sieves include the crystalline aluminophosphate compositions disclosed in U.S. Patent No. 4,310,440 issued January 12, 1982 to Wilson et al. These materials are formed from AlO₂ and PO₂ tetrahedra and have electrovalently neutral frameworks as in the case of silica polymorphs. Unlike the silica molecular sieve, silicalite, which is hydrophobic due to the absence of extra-structural cations, the aluminophosphate molecular sieves are moderately hydrophilic, apparently due to the difference in electronegativity between aluminum and phosphorus. Their intracrystalline pore volumes and pore diameters are comparable to those known for zeolites and silica molecular sieves. In U.S. Patent No. 4,440,871, there is described a novel class of silicon-substituted aluminophosphate non-zeolitic molecular sieves which are both microporous and crystalline. These materials have a three-dimensional crystal framework of PO₂⁺, AlO₂⁻ and SiO₂ tetrahedral units and, exclusive of any alkali metal or calcium which may optionally be present, an as-synthesized empirical chemical composition on an anhydrous basis of: mR : (Si x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (Si x Al y P z )O₂ and has a value of from zero to 0.3, the maximum value in each case depending upon the molecular dimensions of the templating agent and the available void volume of the pore system of the particular silicoaluminophosphate species involved; and "x", "y", and "z" represent the mole fractions of silicon, aluminum and phosphorus, respectively, present as tetrahedral oxides. The minimum value for each of "x", "y", and "z" is 0.01 and preferably 0.02. The maximum value for "x" is 0.98; for "y" is 0.60; and for "z" is 0.52. These silicoaluminophosphates exhibit several physical and chemical properties which are characteristic of both aluminosilicate zeolites and aluminophosphates. In U.S. Patent No. 4,500,651, there is described a novel class of titanium-containing non-zeolitic molecular sieves whose chemical composition in the as-synthesized and anhydrous form is represented by the unit empirical formula: mR: (Ti x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (Ti x Al y P z )O₂ and has a value of between zero and about 5.0; and "x", "y" and "z" represent the mole fractions of titanium, aluminum and phosphorus, respectively, present as tetrahedral oxides. In U.S. Patent No. 4,567,029, there is described a novel class of crystalline metal aluminophosphate non-zeolitic molecular sieves having three-dimensional microporous framework structures of MO₂, AlO₂ and PO₂ tetrahedral units and having an empirical chemical composition on an anhydrous basis expressed by the formula: mR: (M x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (M x Al y P z )O₂ and has a value of from zero to 0.3; "M" represents at least one metal of the group magnesium, manganese, zinc and cobalt; and "x", "y", and "z" represent the mole fractions of the metal "M", aluminum and phosphorus, respectively, present as tetrahedral oxides. In U.S. Patent 4,544,143, there is described a novel class of crystalline ferroaluminophosphate non-zeolitic molecular sieves having a three-dimensional microporous framework structure of FeO₂, AlO₂ and PO₂ tetrahedral units and having an empirical chemical composition on an anhydrous basis expressed by the formula: mR : (Fe x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (Fe x Al y P z )O₂ and has a value of from zero to 0.3; and "x", "y" and "z" represent the mole fractions of the iron, aluminum and phosphorus, respectively, present as tetrahedral oxides. Other aluminophosphate and silicoaluminophosphate non-zeolitic molecular sieves are described in a number of pending patent applications, as described in more detail below. The aforementioned patents and patent applications describe methods for the preparation of the non-zeolitic molecular sieves by hydrothermal crystallization thereof from a substantially homogeneous liquid reaction mixture containing reactive sources of aluminum, phosphorus, silicon (in the case of the silicoaluminophosphates) and the other element(s), if any, required in the non-zeolitic molecular sieve. The reaction mixture also preferably contains an organic templating, i.e., structure-directing, agent, preferably a compound of an element of Group VA of the Periodic Table, and/or optionally an alkali or other metal. The reaction mixture is generally placed in a sealed pressure vessel, preferably lined with an inert plastic material such as polytetrafluoroethylene and heated, preferably under autogenous pressure, at a temperature between 50°C and 250°C, and preferably between 100°C and 200°C, until crystals of the non-zeolitic molecular sieve product are obtained, usually for a period of from several hours to several weeks. Effective crystallization times of from about 2 hours to about 30 days are generally employed. The non-zeolitic molecular sieve is recovered by any convenient method such as centrifugation or filtration. Although these hydrothermal crystallization methods are effective in producing the non-zeolitic molecular sieves in high yields, they have the disadvantage that, presumably because the crystallization of the non-zeolitic molecular sieve takes place from a substantially homogeneous and relatively high viscosity liquid or semi-gel, the average particle size of the non-zeolitic molecular sieve produced is often very small, typically in the sub-micrometer range. This problem of small particle size of the product is especially difficult in the SAPO molecular sieves of U.S. Patent No. 4,440,871, and especially SAPO-34. Such small average particle sizes render the non-zeolitic molecular sieves difficult to filter or centrifuge, and hence difficult to separate cleanly from the reaction mixture in which they are formed. Moreover, the small average particle size of the non-zeolitic molecular sieve tends to cause the same problems (i.e., difficulty of use in some industrial applications, dust hazards, difficulty in binding without reduction and/or modification of adsorptive and catalytic properties, and lack of reproducibility in properties after binding) as with the small average particle size zeolites discussed above. There is thus a need for a process for the production of non-zeolitic molecular sieves which will allow the non-zeolitic molecular sieves to be produced in a form having an average particle size substantially greater than that of the non-zeolitic molecular sieves produced by the hydrothermal crystallization processes described above, and this invention provides such a process. Summary of the Invention Accordingly, this invention provides a process for the production of a crystalline non-zeolitic molecular sieve in a preformed body of alumina or silica-alumina, which process comprises contacting this body with a liquid reaction mixture containing a reactive source of phosphorus pentoxide, and an organic templating agent, the contacting being effected at a time and temperature so as to cause the body to react with the liquid reaction mixture and to form crystals of the non-zeolitic molecular sieve within the body. In this process, if the non-zeolitic molecular sieve is to contain silica, a reactive source of silica (which can be silica itself) may be included in the body and/or in the liquid reaction mixture. Similarly, if the non-zeolitic molecular sieve is to contain one or more elements other than aluminum, silicon and phosphorus, reactive sources of these elements may be included in the silica or silica-alumina body and/or in the liquid reaction mixture. Detailed Description of the Invention The term "non-zeolitic molecular sieves" or "NZMS" as used herein is hereby defined to mean the molecular sieves claimed in the aforementioned U.S. Patents Nos. 4,310,440; 4,440,871; 4,500,651; 4,554,143; and 4,567,029; the AlPO₄-41 molecular sieves described in EP-A-254 075, the "ELAPSO" molecular sieves as disclosed in EP-A-159 624. Certain non-zeolitic molecular sieves ("ELAPO") are disclosed in EP-A-0158976, and EP-A-0158349; and ELAPSO molecular sieves are disclosed in copending EP-A-0159624. The nomenclature employed herein to refer to the members of the aforementioned NZMS's is consistent with that employed in the aforementioned applications or patents. A particular member of a class is generally referred to as a "-n" species wherein "n" is an integer, e.g., SAPO-11, MeAPO-11 and ELAPSO-31. Because the non-zeolitic molecular sieves which can be produced by the process of the present invention comprise such a large number of aluminophosphates and silicoaluminophosphates having a variety of crystal structures, which may include one or more other elements in addition to aluminum, phosphorus and (in the case of the silicoaluminophosphates) silicon, the manner in which these non-zeolitic molecular sieves are produced by the process of the present invention will first be described, and thereafter the chemical nature of the non-zeolitic molecular sieves will be described. PROCESS OF THE INVENTION As already mentioned, in the process of the present invention a body of alumina or silica-alumina (which may optionally contain reactive sources of one or more other elements desired in the non-zeolitic molecular sieve) is contacted with a liquid reaction mixture containing a reactive source of phosphorus pentoxide, and an organic templating agent (and optionally reactive sources of one or more other elements desired in the non-zeolitic molecular sieve), thereby causing the body to react with the liquid reaction mixture and to form crystals of the non-zeolitic molecular sieve within the body of alumina or silica-alumina. In this process, the alumina or silica-alumina in the body reacts with the phosphorus in the liquid reaction mixture to produce the aluminophosphate or silicoaluminophosphate framework structure of the non-zeolitic molecular sieve within the preformed body of alumina or silica-alumina. If one or more elements (other than aluminum, phosphorus, silicon and oxygen) capable of being incorporated into this framework are present in the body or in the liquid reaction mixture, these elements will normally enter into the aluminophosphate or silicoaluminophosphate framework, although the amount of such elements entering the framework will of course vary with the amounts of such elements present,the reactivity of the form of the element employed, and the ease of incorporation of such elements into the framework. If such elements are desired in the non-zeolitic molecular sieve product, they are desirably included in the liquid reaction mixture. In the process of the present invention, the solid body contains alumina (and optionally silica), while the liquid reaction mixture contains a source of phosphorus pentoxide. However, silica may be included in the liquid reaction mixture, either in addition to or in place of silica in the solid body, while the solid body may contain a source of phosphorus pentoxide in addition to that present in the liquid reaction mixture. Although the optimum distribution of silica between the solid body and the solution may vary with a number of factors, including the exact silica source employed, the other components of the reaction mixture, etc., in general incorporation of the silica into the solid body is favored. The alumina or silica-alumina in the body used in the process of the present invention is desirably in an amorphous or poorly crystalline form, since the presence of strongly crystalline alumina or silica-alumina may tend to hinder the formation of the desired crystal form of the non-zeolitic molecular sieve, or even to prevent the formation of this desired form. In order to ensure that the alumina or silica-alumina is in an amorphous or poorly crystalline form, it is desirable that the alumina or silica-alumina be calcined prior to its use in the process of the present invention. Not only does such calcination ensure that the alumina or silica-alumina is in an amorphous or poorly crystalline form, but it also changes the reactivity and accessability of the alumina or silica-alumina , and hence accelerates the reaction of the alumina or silica-alumina with the liquid reaction mixture, and also helps to improve the integrity of the solid body. The optimum calcination temperatures for the alumina or silica-alumina used in the process of the present invention are somewhat lower than those typically used when preparing zeolites from preformed bodies of clay by the prior art processes described above; in general, the preferred calcination temperatures for the alumina or silica-alumina are in the range of from about 250° to about 750°C, although the optimum calcination temperature will vary with the specific alumina or silica-alumina employed. The body of alumina or silica-alumina used in the process of the present invention may have a variety of physical forms. The body may be in the form of small particles. However, in order to facilitate the separation of the non-zeolitic molecular sieve from the liquid reaction mixture after completion of the reaction, and to prepare the non-zeolitic molecular sieve in the form of large particles, it is very much preferred that the alumina or silica-alumina body be a relatively massive body, typically one having a minimum dimension of at least about 0.5 mm. (Effective filtration and washing of the solid product can of course be effected on much smaller particles, such as particles having a diameter of about 60 micrometers, which can be achieved by using spray-dried alumina or silica-alumina bodies in the process of the present invention, as discussed in more detail below.) The body may be shaped into many forms, for example, spheres, microspheres, pellets, beads, tablets, cylinders, disks, granules, cubes or blocks. Suitable shaping techniques for forming such bodies are conventional and include extruding, spray drying, prilling, molding, casting, slip-casting, tableting, briquetting and bead forming processes such as tumbling, drum rolling, Nauta mixing and disk forming. The preferred methods are extrusion, spray drying, prilling and bead forming processes, with extrusion being a particularly preferred technique. When the body is to be formed by extrusion or similar techniques, the first step in its formation is normally the formation of a suspension or paste of alumina (and optionally other ingredients) in a liquid dispersion medium. A variety of techniques may be used to form such a suspension or paste; for example, the suspension or paste may be formed by hydrolyzing an aluminum alkoxide or by peptizing alumina in acid, followed by substantial neutralization of the remaining acid. Alternatively, it may suffice to simply mix the alumina and any other ingredients with water under appropriate agitation, preferably after first grinding or mulling the ingredients to produce them in a finely divided form. The amount of water added should be sufficient to permit formation of shaped bodies from the resultant paste. For most shaping methods the solids content will range from about fifty percent (50%) to about sixty-five percent (65%) by weight of the mixture. The water content will generally range from about 35% to about 45% by weight of the mixture, and preferably about 38% to about 42% by weight. The size of the body may be varied not only by the size of die or other shaping instrument used but also by controlling the composition of the mixture to be shaped and the method of shaping. Typical body sizes range from about 0.4 to about 7 mm. in diameter if the particle is approximately spherical or cylindrical in form. Smaller bodies, often as small as about fifty (50) to about ninety (90) micrometers in average diameter, result if they are shaped by some spray drying and prilling techniques. Once shaped, the bodies are ready for calcination. Prior to this step, however, they may optionally be dried at a temperature of about 50° to about 150°C for about 0.5 to 36 hours. In the interest of time and expense, however, calcination is generally done immediately after shaping. The drying and/or calcination serves to remove at least part of the liquid dispersion medium added to the alumina or silica-alumina prior to the extrusion or other shaping of the body. The alumina in the alumina or silica-alumina body may be in any form which is sufficiently reactive to react with the liquid reaction mixture; thus, for example, most of the forms of alumina used in the zeolite synthesis processes described above may also be used in the process of the present invention. The preferred forms of alumina include boehmite and pseudoboehmite. When the body is to contain silica, almost any reactive silicon source may be employed such that SiO₂ tetrahedral units are formed in situ . The silicon source may be silica in the form of a silica sol, may be a fumed silica or may be other conventional sources of silica used in zeolite synthesis such as reactive solid amorphous precipitated silicas, silica gel, alkoxides of silicon, tetraalkyl orthosilicates (for example, tetraethyl orthosilicate), silicic acid, alkali metal silicates and the like. Preferred silica sources are colloidal silica and silica sols. Also, when the body is to contain silica, an aluminosilicate clay, such as a kaolin, may be used as a source of both silica and alumina, although it should be noted that in some cases the use of an aluminosilicate clay may be disadvantageous because silica from such clays may not be readily available for incorporation into the non-zeolitic molecular sieve, if the calcination temperature employed is inappropriate. When the alumina or silica-alumina body is to contain one or more elements other than aluminum, silicon and oxygen for incorporation into the non-zeolitic molecular sieve, the other element(s) may be in the form of the compounds of such elements discussed below, subject to the proviso that the other elements should not be present in a form which significantly interferes with the formation of the alumina or silica-alumina body. The liquid reaction mixture used in the process of the present invention comprises a reactive source of phosphorus. The reactive phosphorus source is preferably orthophosphoric acid or a salt thereof, and desirably the liquid reaction mixture comprises an aqueous solution of orthophosphoric acid or a salt thereof. Organic phosphates such as triethyl phosphate may also be employed. Organophosphorus compounds, such as tetrabutylphosphonium bromide, do not, apparently, serve as reactive sources of phosphorus, but these compounds do function as templating agents. Conventional phosphorus salts, such as sodium metaphosphate, may be used, at least in part, as the phosphorus source, but are not preferred. The liquid reaction mixture used in the process of the present invention also contains an organic templating agent. This organic templating agent can be any of those heretofore proposed for use in the synthesis of conventional zeolite aluminosilicates or NZMS's. In general these compounds contain elements of Group VA of the Periodic Table of Elements, particularly nitrogen, phosphorus, arsenic and antimony, preferably nitrogen or phosphorus and most preferably nitrogen, which compounds also contain at least one alkyl or aryl group having from 1 to 8 carbon atoms. Particularly preferred compounds for use as templating agents are the amines, quaternary phosphonium and quaternary ammonium compounds, the latter two being represented generally by the formula R₄X⁺ wherein "X" is phosphorus or nitrogen and each R is an alkyl or aryl group containing from 1 to 8 carbon atoms. Polymeric quaternary ammonium salts such as [(C₁₄H₃₂N₂)(OH)₂] x wherein x has a value of at least 2 are also suitably employed. The mono-, di- and tri-amines are advantageously utilized, either alone or in combination with a quaternary ammonium compound or other templating compound. Mixtures of two or more templating agents can either produce mixtures of the desired non-zeolitic molecular sieves or the more strongly directing templating species may control the course of the reaction with the other templating species serving primarily to establish the pH conditions of the reaction gel. Representative templating agents include tetramethylammonium, tetraethylammonium, tetrapropylammonium and tetrabutylammonium ions; tetrapentylammonium ion; di-n-propylamine; tripropylamine; triethylamine; triethanolamine; piperidine; cyclohexylamine; 2-methylpyridine; N,N-dimethylbenzylamine; N,N-diethylethanolamine; dicyclohexylamine; N,N-dimethylethanolamine; choline; N,N-dimethylpiperazine; 1,4-diazabicyclo-(2,2,2)-octane; N-methyldiethanolamine; N-methylethanolamine; N-methylpiperidine; 3-methylpiperidine; N-methylcyclohexylamine; 3-methylpyridine; 4-methylpyridine; quinuclidine; N,N′-dimethyl-1,4-diazabicyclo-(2,2,2)-octane ion; di-n-butylamine; neopentylamine; di-n-pentylamine; isopropylamine; t-butylamine; ethylenediamine; pyrrolidine; and 2-imidazolidone. Not every templating agent will direct the formation of every species of non-zeolitic molecular sieve but a single templating agent can, with proper manipulation of the reaction conditions, direct the formation of several non-zeolitic molecular sieve compositions, and a given non-zeolitic molecular sieve composition can be produced using several different templating agents. When the liquid reaction mixture is to contain a source of silica, this source of silica may be any of those silica sources already mentioned for use in the silica-alumina body provided that the silica source is capable of being dissolved and/or dispersed in the liquid reaction mixture. Preferred silica sources for use in the liquid reaction mixture are silica sols. When the liquid reaction mixture is to contain a source of one or more elements other than phosphorus, silicon and oxygen for incorporation into the non-zeolitic molecular sieve, the other element(s) may be introduced into the liquid reaction mixture in any form which permits the formation in situ of a reactive form of the desired elements, i.e., a form reactive to form the framework tetrahedral oxide unit of the elements present in the non-zeolitic molecular sieve. Compounds of the elements which may be employed include oxides, alkoxides, hydroxides, chlorides, bromides, iodides, sulfates, nitrates, carboxylates (e.g., acetates) and the like. Especially preferred sources of various elements are discussed in the description of the various groups of non-zeolitic molecular sieves given below. Similarly, when the solid body is to contain a source of phosphorus, this source of phosphorus may be any of those phosphorus sources already mentioned for use in the liquid reaction mixture provided that the phosphorus source is capable of being incorporated into the solid body without interfering with the process of the present invention. Those skilled in the art will also be aware of other, sparingly-soluble phosphorus sources which may be usable in the solid body. The proportions of the various components in the liquid reaction mixture, and the ratios of these components to the alumina (and optionally silica and other elements) present in the solid body, affect, inter alia , the rate at which the process of the present invention progresses and the yield and composition of the non-zeolitic molecular sieve produced. In general, the proportions of the various components of the reaction mixture (including the body) used in the process of the present invention are similar to those used in the hydrothermal crystallization processes described in the aforementioned patents and pending patent applications describing non-zeolitic molecular sieves, although in the case of components present in the solid body allowance may have to be made for the possibility of incomplete reaction or conversion of such components, especially if the solid body is formed from clay. Thus, in synthesizing non-zeolitic molecular sieves by the process of the present invention, it is preferred to employ a liquid reaction mixture comprising not more than about 6, and desirably not more than about 2, moles of the organic templating agent per mole of phosphorus. Preferably, the liquid reaction mixture contains not more than 500, desirably not more than about 100, and most desirably not more than about 50, moles of water per mole of phosphorus. When the liquid reaction mixture contains silica, the liquid reaction mixture desirably contains from about 0.1 to about 0.5 moles of silicon per mole of phosphorus. The proportions of elements other than phosphorus, silicon and oxygen, intended for incorporation into the non-zeolitic molecular sieve, to be included in the liquid reaction mixture will vary both with the proportion of such elements desired in the non-zeolitic molecular sieve to be produced and the ease with which such elements enter the crystal framework of the non-zeolitic molecular sieve. General guidance concerning the appropriate proportions of individual elements to be included in the liquid reaction mixture is given in the description of the various groups of non-zeolitic molecular sieves below. The weight ratio of the body to the liquid reaction mixture is desirably adjusted so that the body comprises from about 0.75 to about 1.25 moles of aluminum per mole of phosphorus in the liquid reaction mixture. In those cases in which an alkoxide is employed as the source of aluminum, phosphorus, silicon, or other elements desired in the non-zeolitic molecular sieve, the corresponding alcohol is necessarily present in the reaction mixture since it is a hydrolysis product of the alkoxide. It has not been determined whether this alcohol participates in the synthesis process as a templating agent. For the purposes of this application, however, this alcohol is arbitrarily omitted from the class of templating agents, even if it is present in the as-synthesized non-zeolitic molecular sieve. In general, the liquid reaction mixture used in the process of the present invention is prepared by forming mixtures of less than all of the reagents and thereafter incorporating into these mixtures additional reagents either singly or in the form of other intermediate mixtures of two or more reagents. In some instances the reagents admixed retain their identity in the intermediate mixture and in other cases some or all of the reagents are involved in chemical reactions to produce new reagents. The term "mixture" is applied in both cases. Furthermore, it is preferred that the intermediate mixtures as well as the final reaction mixtures be stirred until substantially homogeneous. In the process of the present invention, the reaction mixture is generally placed in a sealed pressure vessel, preferably lined with an inert plastic material such as polytetrafluoroethylene (to avoid contamination of the reaction mixture) and heated, preferably under autogenous pressure, at a temperature between 100°C and 300°C, and preferably between 150°C and 250°C, until crystals of the non-zeolitic molecular sieve product are obtained, usually for a period of from several hours to several weeks. Effective crystallization times of from about 2 hours to about 30 days are generally employed with from about 24 to about 240 hours, and preferably about 48 hours to about 144 hours, being typically employed. While not essential to the synthesis of the non-zeolitic molecular sieve compositions, stirring or other moderate agitation of the reaction mixture and/or seeding the reaction mixture with seed crystals of either the non-zeolitic molecular sieve species to be produced or a topologically similar aluminophosphate, aluminosilicate or molecular sieve composition, facilitates the crystallization procedure. The product is recovered by any convenient method such as centrifugation or filtration. It is one significant advantage of the process of the present invention that this process is capable of producing then non-zeolitic molecular sieve product in a form having a considerably larger average particle size than that of the non-zeolitic molecular sieve produced by the hydrothermal crystallization processes for the synthesis of non-zeolitic molecular sieves described in the relevant patents and copending applications mentioned above. Optimally, the non-zeolitic molecular sieve is produced as a single solid body having substantially the same size and shape as the alumina or silica-alumina body used in the synthesis. Even though this optimum result is not usually obtained, and some fragmentation of the alumina or silica-alumina body may occur, the non-zeolitic molecular sieve is still produced in a form having a considerably larger average particle size than that of the non-zeolitic molecular sieves produced by the aforementioned hydrothermal crystallization processes. Whereas these hydrothermal crystallization processes typically produce particles of non-zeolitic molecular sieves having average particle sizes in the sub-micrometer range, the process of the present invention usually produces a product having an average particle size of at least about 10 micrometers, and preferably from about 20 to about 40 micrometers or more. After crystallization the non-zeolitic molecular sieve product may be isolated and advantageously washed with water and dried in air. The as-synthesized non-zeolitic molecular sieve generally contains within its internal pore system at least one form of the templating agent employed in its formation. Most commonly the organic moiety derived from an organic template is present, at least in part, as a charge-balancing cation as is generally the case with as-synthesized aluminosilicate zeolites prepared from organic-containing reaction systems. It is possible, however, that some or all of the organic moiety is an occluded molecular species in a particular non-zeolitic molecular sieve species. As a general rule the templating agent, and hence the occluded organic species, is too large to move freely through the pore system of the non-zeolitic molecular sieve product and must be removed by calcining the non-zeolitic molecular sieve at temperatures of 200°C to 700°C, and preferably 350°C to 600°C, to thermally degrade the organic species. In a few instances the pores of the non-zeolitic molecular sieve product are sufficiently large to permit transport of the templating agent, particularly if the latter is a small molecule, and accordingly complete or partial removal thereof can be accomplished by conventional desorption procedures such as are carried out in the case of zeolites. It will be understood that the term "as-synthesized" as used herein does not include the condition of the non-zeolitic molecular sieve phase wherein the organic moiety occupying the intracrystalline pore system as a result of the synthesis process has been reduced by post-synthesis treatment such that less than 0.02 moles of templating agent are present in the intracrystalline pore system per two gram atoms of oxygen present therein. The non-zeolitic molecular sieve compositions produced by the process of the present invention may exhibit cation-exchange capacity when analyzed using ion-exchange techniques heretofore employed with zeolitic aluminosilicates and have pore diameters which are inherent in the lattice structure of each species and which are at least about 0,3nm (3Å) in diameter. Ion exchange of non-zeolitic molecular sieve compositions is ordinarily possible only after the organic moiety present as a result of synthesis has been removed from the pore system. Dehydration to remove water present in the as-synthesized non-zeolitic molecular sieve compositions can usually be accomplished, to some degree at least, in the usual manner without removal of the organic moiety, but the absence of the organic species greatly facilitates adsorption and desorption procedures. The non-zeolitic molecular sieve materials have various degrees of hydrothermal and thermal stability, some being quite remarkable in this regard, and will function as molecular sieve adsorbents and hydrocarbon conversion catalysts or catalyst bases. As is well known to those familiar with the use of molecular sieves as catalysts, the reaction rate of a molecular sieve-catalyzed reaction is often strongly influenced by the pore size of the molecular sieve, since the catalytic activity of molecular sieves appears to depend upon the ability of the reactants and products to diffuse through the pores of the molecular sieve. The pore sizes of the non-zeolitic molecular sieves produced by the process of the present invention vary over a wide range, and on the basis of pore size, the non-zeolitic molecular sieves may be divided into small, medium and large pore materials. The small pore materials are those having, in their calcined form, an adsorption of isobutane of less than about 2 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 667 mbar (500 torr) and a temperature of 20°C. The medium pore materials are those having, in their calcined form, an adsorption of isobutane of at least about 2 percent, and preferably at least about 4 percent, by weight of the non-zeolitic molecular sieve at a partial pressure of 667 mbar (500 torr) and a temperature of 20°C, and an adsorption of triethylamine of less than 5 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 3,5 mbar (2.6 torr) and a temperature of 22°C. The large pore materials are those having, in their calcined form, an adsorption of isobutane of at least about 2 percent, and an adsorption of triethylamine of at least 5 percent, by weight of the non-zeolitic molecular sieve at a partial pressure of 3,5 mbar (2.6 torr) and a temperature of 22°C. An adsorption of isobutane of at least about 2 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 667 mbar (500 torr) and a temperature of 20°C corresponds to a minimum pore size of approximately 0,5nm (5Å), while an adsorption of triethylamine of less than 5 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 3,5 mbar (2.6 torr) and a temperature of 22°C corresponds to a maximum pore size of approximately 0,7nm (7Å). In most of the catalytic processes in which the NZMS's produced by the process of the present invention are employed, medium and large pore materials are preferred, since such medium and large pore non-zeolitic molecular sieves have pores sufficiently large to permit proper diffusion of all molecular species involved in the reaction. Accordingly, in a preferred form of the process of the present invention, the NZMS produced is a medium or large pore material. Medium and large pore NZMS's include, but are not limited to, ELAPSO-5, ELAPSO-11, ELAPSO-31, ELAPSO-36, ELAPSO-37, ELAPSO-40, ELAPSO-41, SAPO-5, SAPO-11, SAPO-31, SAPO-36, SAPO-37, SAPO-40, SAPO-41, CoAPSO-5, CoAPSO-11, Co-APSO-31, CoAPSO-36, CoAPSO-37, CoAPSO-40, CoAPSO-41, FeAPSO-5, FeAPSO-11, FeAPSO-31, FeAPSO-36.

The above characterization of the NZMS's employed in the instant invention relates to an adsorption characterization that is carried out on a NZMS which has been subjected to a post synthesis treatment, e.g., calcination or chemical treatment, to remove a substantial portion of the template, "R", which is present as a result of synthesis. Although a particular NZMS may be characterized herein by reference to its adsorption of isobutane in its calcined form, the instant invention necessarily synthesizes a non-calcined or modified NZMS which may be characterized by such adsorption in its calcined form, since upon use of such a non-calcined NZMS in various catalytic processes under effective process conditions the NZMS may be calcined or hydrothermally treated in situ so as to have the characteristic adsorption of isobutane. Thus, the NZMS may be converted in situ to a form characterized by the aforementioned adsorption characteristics. For example, an as-synthesized MgAPO-11 or MgAPSO-11 may not be characterized by the aforementioned adsorption of isobutane due to the presence of template "R" which is present as a result of synthesis, although the calcined form of MgAPO-11 and MgAPSO-11 will be characterized by the aforementioned adsorption of isobutane. Thus, in this application, reference to a NZMS having a particular adsorption characteristic in its calcined or anhydrous form is not intended to exclude the use of this NZMS in its as-synthesized form which upon in-situ calcination, hydrothermal treatment and/or other treatment, e.g., ion exchange with suitable ions, would have such adsorption characteristics. As explained in the aforementioned patents and applications describing non-zeolitic molecular sieves, the non-zeolitic molecular sieves may be characterized by their X-ray powder diffraction patterns, i.e., the various crystal forms of each non-zeolitic molecular sieve, for example SAPO-11, SAPO-34, SAPO-41, etc., may be identified and distinguished from one another by their X-ray powder diffraction patterns. Since some of the non-zeolitic molecular sieves produced in the Examples below are thus characterized, the following explanation is given of the manner in which these X-ray powder diffraction patterns are obtained. X-Ray patterns of reaction products are obtained by X-ray analysis, using standard X-ray powder diffraction techniques. The radiation source is a high-intensity X-ray tube with a copper target operated at 50 kV and 40 mA. The diffraction pattern from the copper K-alpha radiation and graphite monochromator is suitably recorded by an X-ray spectrometer scintillation counter, pulse height analyzer and strip chart recorder. Flat compressed powder samples are scanned at 2° (2 theta) per minute, using a two second time constant. Interplanar spacings (d) in Angstrom Units are obtained from the position of the diffraction peaks expressed as 2ϑ, where ϑ is the Bragg angle, as observed on the strip chart. Intensities were determined from the heights or areas of diffraction peaks after substracting background, "I o " being the intensity of the strongest line or peak, and "I" being the intensity of each of the other peaks. Alternatively, the X-ray patterns may be obtained by use of computer-based techniques using copper K-alpha radiation, Siemens type K-805 X-ray sources and Siemens D-500 X-ray powder diffractometers available from Siemens Corporation, Cherry Hill, N.J. As will be understood by those skilled in the art, the determination fo the parameter 2 theta is subject to both human and mechanical error, which in combination can impose an uncertainty of about ±0.4° on each reported value of 2 theta. This uncertainty is, of course, also manifested in the reported values of the d-spacings, which are calculated from the 2 theta values. This imprecision is general throughout the art and is not sufficient to preclude the differentiation of the non-zeolitic molecular sieves from each other and from the compositions of the prior art. In certain instances hereinafter in the illustrative examples, the purity of a synthesized non-zeolitic molecular sieve product may be assessed with reference to its X-ray powder diffraction pattern. Thus, for example, if a sample is stated to be pure, it is intended only to mean that the X-ray pattern of the sample is free of lines attributable to crystalline impurities, not that there are no amorphous materials present. In the illustrative examples below, when the non-zeolitic molecular sieves produced by the process of the present invention are characterized by their X-ray powder diffraction patterns, these X-ray patterns are for the as-synthesized form unless otherwise noted. In most cases, the pattern of the corresponding calcined form will also fall within the relevant table. However, in some cases the removal of the occluded templating agent which occurs during calcination will be accompanied by sufficient relaxation of the lattice to shift some of the lines slightly outside the ranges specified in the relevant table. In a small number of cases, calcination appears to cause more substantial distortion in the crystal lattice, and hence, more significant changes in the X-ray powder diffraction pattern. After synthesis and (optionally) calcination, a non-zeolitic molecular sieve produced by the process of the present invention may be modified by depositing or impregnating the non-zeolitic molecular sieve with cations, anions or salts so as to improve its efficacy as a catalyst in the various processes in which non-zeolitic molecular sieves are useful, as described in the aofrementioned patents and applications describing non-zeolitic molecular sieves. Techniques which may be employed to effect the deposition or impregnation of a non-zeolitic molecular sieve are generally known in the art. Such procedures may involve (1) impregnating the non-zeolitic molecular sieve with a solution comprising a solvent or solubilizing agent of one or more such modifying materials in an amount sufficient to deposit the desired weight of such materials in the non-zeolitic molecular sieve and/or (2) exchanging the non-zeolitic molecular sieve with a solution containing the modifying material. The impregnation or deposition of the modifying materials may generally be accomplished by heating the non-zeolitic molecular sieve at an elevated temperature to evaporate any liquid present to effect deposition or impregnation of the modifying material on to the interior and/or exterior surface of the non-zeolitic molecular sieve, or by the exchange of cations present in the non-zeolitic molecular sieve with cations that provide for the desired properties. Alternatively, the modifying material may be formed on the non-zeolitic molecular sieve from an emulsion or slurry containing the modifying material by heating the non-zeolitic molecular sieve. Impregnation or exchange procedures are generally the preferred techniques because they utilize and introduce the modifying material more efficiently than other procedures such as coating procedures, since a coating procedure is generally not able to effect substantial introduction of the modifying material on to the interior surfaces of the non-zeolitic molecular sieve. In addition, coated materials are more generally susceptible to the loss of the modifying materials by abrasion. Suitable modifying materials include alkali metals, alkaline earth metals, transition metals and the salts thereof, including inorganic and organic salts such as nitrates, halides, hydroxides, sulfates and carboxylates. Other modifying materials generally employed in the art are also believed to be employable in the non-zeolitic molecular sieves. The non-zeolitic molecular sieves may be admixed (blended) or provided sequentially to other materials which may provide some property which is beneficial under certain process conditions, such as improved temperature resistance or improved catalyst life by minimization of coking, or which are simply inert under the process conditions used. Such materials may include synthetic or naturally-occurring substances as well as inorganic materials such as clays, silicas, aluminas, crystalline aluminosilicate zeolites, metal oxides and mixtures thereof. In addition, the non-zeolitic molecular sieves may be formed with materials such as silica, alumina, silica-alumina, silica-magnesia, silica-zirconia, silica-thoria, silica-berylia, and silica-titania, as well as ternary compositions, such as silica-alumina-thoria, silica-alumina-zirconia and clays present as binders. The relative proportions of the above materials and the non-zeolitic molecular sieves may vary widely with the non-zeolitic molecular sieve content ranging between about 1 and about 99 percent by weight of the composite. The foregoing general description of the process of the present invention is applicable to its use in synthesizing all the non-zeolitic molecular sieves described in the aforementioned patents and applications describing such materials. The following more specific description details preferred variants of the process of the present invention for the synthesis of certain preferred groups of non-zeolitic molecular sieves. One preferred group of non-zeolitic molecular sieves to be produced by the process of the present invention is the aluminophosphates (AlPO₄'s) claimed in U.S. Patent No. 4,310,440, especially AlPO₄-5. The preferred organic templating agents for the synthesis of the AlPO₄'s are tetraethylammonium hydroxide, tetrapropylammonium hydroxide, diethylethanolamine and tripropylamine. The particularly preferred organic templating agent for this synthesis is a mixture of tetraethylammonium hydroxide and tripropylamine, with the liquid reaction mixture containing from about 0.1 to about 0.4 moles of tetraethylammonium hydroxide and from about 0.5 to about 2 moles of tripropylamine per mole of phosphorus. In this synthesis, the body of alumina is preferably contacted with the liquid reaction mixture at a temperature in the range of from about 100° to about 200°C for a period of from about 12 to about 72 hours. A second preferred group of non-zeolitic molecular sieves to be produced by the process of the present invention is the silicoaluminophosphates (SAPO's) claimed in U.S. Patent No. 4,440,871, desirably SAPO-5, SAPO-11, SAPO-34 and SAPO-41, and most desirably SAPO-34. The preferred organic templating agents for the synthesis of SAPO's are tetraethylammonium hydroxide, diethanolamine and di-n-propylamine. The particularly preferred organic templating agent for this synthesis is a mixture of diethanolamine and di-n-propylamine, with the liquid reaction mixture containing from about 0.5 to about 2 moles of diethanolamine and from about 0.1 to about 0.5 moles of di-n-propylamine per mole of phosphorus. In this synthesis the body of alumina or silica-alumina is desirably calcined at a temperature of from about 250° to about 450°C prior to being contacted with the liquid reaction mixture. Also in this synthesis, the body of alumina or silica-alumina is desirably contacted with the liquid reaction mixture at a temperature in the range of from about 150° to about 250°C for a period of from about 48 to about 144 hours. Certain of the Examples below also illustrate the synthesis, by the process of the present invention of certain GeAPO and GeAPSO non-zeolitic molecular sieves claimed in the aforementioned copending applications Serial Nos. 841,758 and 852,175 respectively. The following Examples are provided to further illustrate the process of the present invention, but are not limitative thereof. EXAMPLES The following Examples illustrate the synthesis of AlPO₄-5, SAPO-5, SAPO-11, SAPO-34, SAPO-41, CoAPSO-34, GeAPO-5, GeAPO-17 and GeAPSO-34 by the process of the present invention. The characteristic X-ray table for AlPO₄-5 is given in U.S. Patent 4,310,440 at Table 2 in column 8. The characteristic X-ray tables for SAPO-5, SAPO-11, SAPO-34 and SAPO-41 are given in U.S. Patent 4,440,871 at Tables I, III, XI and XXV in columns 20, 27, 44 and 69 respectively.

Example 1 395.4 Grams of aluminum isopropoxide (containing 25.8 percent by wt. of Al₂O₃) were placed in the mixing bowl of a Hobart mixer, sufficient water was added to make an extrudable paste, and the mixture was mixed until a substantially homogeneous paste was formed. This paste was extruded using a domestic kitchen meat grinder attachment fitted with a (1/8 inch) (3,175 mm) die, thereby forming extruded alumina precursor cylinders 3,175 mm (1/8 inch) in diameter. These extruded cylinders were air-dried for several days and were then heated in air to 350°C for 2.5 hours. The moisture content of the resultant alumina bodies was less than 1 wt. percent.

This alumina/silica mixture was blended for approximately 10 minutes. To the blended mixture was added sufficient additional water to make an extrudable paste, and the mixture was mixed for a further 20 minutes until a substantially homogeneous paste was formed. The resultant paste was extruded in the same way as in Example 1 above, and the extruded cylinders were oven-dried at 100°C for 16 hours. The oven-dried cylinders were divided into three portions, which were then heated in air for 2.5 hours at the following temperatures: A - 350°C B - 400°C C - 500°C.

Example 7 11 Pounds (approximately 4.9 kilograms) of hydrated aluminum oxide in the form of a pseudoboehmite phase containing 69.0 wt. percent of Al₂O₃ and 31.0 wt. percent of H₂O were blended in a muller with approximately 5 liters of water for 30 minutes until a substantially homogeneous paste was formed. The resultant paste was extruded using a 5 inch (127 mm.) barrel extruder with a 1/8 inch (approximately 3 mm.) die and the extruded cylinders were oven-dried at 100°C for 16 hours and were then heated in air at 350°C for 2.5 hours.

Example 10 551.68 Grams of kaolin clay having a molar oxide ratio of 2 SiO₂ : Al₂O₃ : 2H₂O were blended dry in a Hobart mixer for approximately 30 minutes with 29.94 grams of an attapulgite clay and 50.0 grams of a burn-out mixture. To the blended mixture was added sufficient water to make an extrudable paste, and the mixture was mixed for a further 30 minutes until a substantially homogeneous paste was formed. The resultant paste was extruded in the same way as in Example 1 above, and the extruded cylinders were oven-dried at 100°C for 24 hours and then heated with an air purge at 650°C for 1.5 hours.

In one embodiment the reaction mixture is selected such that the mole fractions "w", "x", "y" and "z" are generally defined as being within the limiting compositional values or points as follows: Point Mole Fraction x y (z + w) F 0.60 0.38 0.02 G 0.38 0.60 0.02 H 0.01 0.60 0.39 I 0.01 0.01 0.98 J 0.60 0.01 0.39 In the foregoing expression of the reaction composition, the reactants are normalized with respect to the total of "w", "x" "y" and "z" such that (w + x + y + z) = 1.00 mole. Preparative Reagents LiAPSO compositions may be prepared by using numerous reagents. Reagents which may be employed to prepare LiAPSOs include: (a) Alipro: aluminum isopropoxide; (b) CATAPAL; Trademark of Condea Corporation for hydrated pseudoboehmite; (c) LUDOX-LS: LUDOX-LS is the tradename of DuPont for an aqueous solution of 30 weight percent SiO₂ and 0.1 weight percent Na₂O; (d) H₃PO₄: 85 weight percent aqueous phosphoric acid; (e) lithium orthophosphate; (f) TEAOH: 40 weight percent aqueous solution of tetraethylammonium hydroxide; (g) TBAOH: 40 weight percent aqueous solution of tetrabutylammonium hydroxide; (h) Pr₂NH: di-n-propylamine, (C₃H₇)₂NH; (i) Pr₃N: tri-n-propylamine, (C₃H₇)₃N; (j) Quin: Quinuclidine, (C₇H₁₃N); (k) MQuin: Methyl Quinuclidine hydroxide, (C₇H₁₃NCH₃OH); (l) C-hex: cyclohexylamine; (m) TMAOH: tetramethylammonium hydroxide; (n) TPAOH: tetrapropylammonium hydroxide; and (o) DEEA: 2-diethylaminoethanol; (p) Tetraalkylorthosilicates, such as tetraethylorthosilicate. ALUMINOPHOSPHATE MOLECULAR SIEVES The various classes of aluminophosphate non-zeolitic molecular sieves will now be described. AlPO₄ ALUMINOPHOSPHATE MOLECULAR SIEVES The AlPO₄ aluminophosphate molecular sieves of U.S. Patent No. 4,310,440 are disclosed as microporous crystalline aluminophosphates having an essential crystalline framework structure whose chemical composition, expressed in terms of molar ratios of oxides, is: Al₂O₃ : 0.8-1.2 P₂O₅. The pores of the framework structure are uniform and in each species have nominal diameters of from 3 to 10 Angstroms; the aluminophosphates have an intracrystalline adsorption capacity for water at 4.6 Torr and 24°C of at least 3.5 weight percent, the adsorption of water being completely reversible while retaining the same essential framework topology in both the hydrated and dehydrated state. By the term "essential framework topology" is meant the spatial arrangement of the primary Al-O and P-O bond linkages. No change in the framework topology indicates that there is no disruption of these primary bond linkages. In the as-synthesized form, the structure-directing agent is contained within the framework structure of the aluminophosphate in amounts which vary from species to species but usually do not exceed one mole per mole of Al₂O₃ thereof. This structure-directing agent is readily removed by water washing or calcination and does not appear to be an essential constituent of the aluminophosphate, as evidenced by essentially complete absence of ion-exchangeability of the as-synthesized compositions and also the complete absence of any internally-contained organic molecules in the as-synthesized form of at least one species of the generic class. Evidence that structure-directing agent is a critical constituent is contained in certain of the Examples of the Patent 4,310,440, wherein reaction mixtures, otherwise identical to those which yield the AlPO₄ products except for the presence of templating agents, yield instead the previously known aluminophosphate phases AlPO₄.I.I-1.3 H₂O, AlPO₄-tridymite, AlPO₄-quartz and AlPO₄-cristobalite. The AlPO₄ aluminophosphates may be prepared by forming a reaction mixture which contains, in terms of molar ratios of oxides: Al₂O₃ : 0.5-1.5 P₂O₅ : 7-100 H₂O and contains from about 0.2 to 2.0 moles of templating agent per mole of Al₂O₃. MeAPO MOLECULAR SIEVES MeAPO molecular sieves are crystalline microporous aluminophosphates in which the substituent metal is one of a mixture of two or more divalent metals of the group magnesium, manganese, zinc and cobalt and are disclosed in U.S. Patent No. 4,567,029. Members of this novel class of compositions have a three-dimensional microporous crystal framework structure of MO₂⁻², AlO⁻₂ and PO⁺₂ tetrahedral units and have an essential empirical chemical composition, on an anhydrous basis, of: mR : (M x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (M x Al y P z )O₂ and has a value of from zero to 0.3, the maximum value in each case depending upon the molecular dimensions of the templating agent and the available void volume of the pore system of the particular metal aluminophosphate involved; "x", "y", and "z" represent the mole fractions of the metal "M", (i.e., magnesium, manganese, zinc and cobalt), aluminum and phosphorus, respectively, present as tetrahedral oxides, said mole fractions being such that they are representing the following values for "x", "y", and "z": Point Mole Fraction x y z A 0.01 0.60 0.39 B 0.01 0.39 0.60 C 0.35 0.05 0.60 D 0.35 0.60 0.05 When synthesized the minimum value of "m" in the formula above is 0.02. In a preferred subclass of the metal aluminophosphates of this invention, the values of "x", "y" and "z" in the formula above are representing the following values for "x", "y" and "z": Point Mole Fraction x y z a 0.01 0.52 0.47 b 0.01 0.39 0.60 c 0.25 0.15 0.60 d 0.25 0.40 0.35 The as-synthesized compositions are capable of withstanding 350°C calcination in air for extended periods, i.e., at least 2 hours without becoming amorphous. While it is believed that the M, Al and P framework constituents are present in tetrahedral coordination with oxygen, it is theoretically possible that some minor fraction of these framework constituents are present in coordination with five or six oxygen atoms. It is not, moreover, necessarily the case that all of the M, Al and/or P content of any given synthesized product is a part of the framework in the aforesaid types of coordination with oxygen. Some of each constituent may be merely occluded or in some as yet undetermined form and may or may not be structurally significant. Since the term "metal aluminophosphate" is somewhat cumbersome, particularly in view of the need for numerous repetitions thereof in describing such compositions, the "short-hand" reference "MeAPO" is emplyed hereinafter. Also in those cases where the metal "Me" in the composition is magnesium, the acronym MAPO is applied to the composition. Similarly, ZAPO, MnAPO, and CoAPO are applied to the compositions which contain zinc, manganese and cobalt, respectively. To identify the various structural species which make up each of the subgeneric classes MAPO, ZAPO, CoAPO and MnAPO, each species is assigned a number and is identified, for example, as ZAPO-5, MAPO-11, CoAPO-11 and so forth. The term "essential empirical chemical composition" is meant to include the crystal framework and can include any organic templating agent present in the pore system, but does not include alkali metal or other ions which can be present by virtue of being contained in the reaction mixture or as a result of post-synthesis ion-exchange. Such ionic species, when present, function primarily as charge-balancing ions for AlO₂⁻ and/or MO₂⁻² tetrahedra not associated with PO₂⁺ tetrahedra or an organic ion derived from the organic templating agent. In synthesizing the MeAPO compositions, it is preferred to employ a reaction mixture composition expressed in terms of molar ratios as follows: aR : (M x Al y P z )O₂ : bH₂O wherein "R" is an organic templating agent; "a" has a value great enough to constitute an effective concentration of "R" and is within the range of >0 to 6; "b" has a value of from zero to 500, preferably 2 to 30; "M" represents a metal of the group zinc, magnesium, manganese and cobalt, "x", "y" and "z" represent the mole fractions, respectivel, of "M", aluminum and phosphorus in the (M x Al y P z )O₂ constituent, and each has a value of at least 0.01, the said points E, F, G, H, I, and J representing the following values for "x", "y" and "z": Point Mole Fraction x y z E 0.01 0.70 0.29 F 0.01 0.29 0.70 G 0.29 0.01 0.70 H 0.40 0.01 0.59 I 0.40 0.59 0.01 J 0.29 0.70 0.01 In the foregoing expression of the reaction composition, the reactants are normalized with respect to a total of (M + Al + P) = (x + y + z) = 1.00 mole. The metals zinc, cobalt, magnesium and manganese can be introduced into the reaction system in any form which permits the formation in situ of reactive divalent ions of the respective metals. Advantageously salts, oxides or hydroxides of the metals are employed such as cobalt chloride hexahydrate, alpha cobaltous iodide, cobaltous sulfate, cobalt acetate, cobaltous bromide, cobaltous chloride, zinc acetate, zinc bromide, zinc formate, zinc iodide, zinc sulfate heptahydrate, magnesium acetate, magnesium bromide, magnesium chloride, magnesium iodide, magnesium nitrate, magnesium sulfate, manganous acetate, manganous bromide, manganous sulfate, and the like. FAPO MOLECULAR SIEVES Ferroaluminophosphates are disclosed in U.S. Patent No. 4,554,143, and have a three-dimensional microporous crystal framework structure of AlO₂, FeO₂, and PO₂ tetrahedral units and have an essential empirical chemical composition, on an anhydrous basis, of: mR : (Fe X Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (Fe x Al y P z )O₂ and has a value of from zero to 0.3, the maximum value in each case depending upon the molecular dimensions of the templating agent and the available void volume of the pore system of the particular ferroaluminophosphate involved ; "x", "y", and "z" represent the mole fractions of iron, aluminum and phosphorus, respectively, present as tetrahedral oxides, representing the following values for "x", "y", and "z": Point Mole Fraction x y z A 0.01 0.60 0.39 B 0.01 0.39 0.60 C 0.35 0.05 0.60 D 0.35 0.60 0.05 When synthesized the minimum value of "m" in the formula above is 0.02. In a preferred subclass of the ferroaluminophosphates the values of "x", "y", and "z" in the formula above are representing the following values for "x", "y", and "z": Point Mole Fraction x y z a 0.01 0.52 0.47 b 0.01 0.39 0.60 c 0.25 0.15 0.60 d 0.25 0.40 0.35 The iron of the FeO₂ structural units can be in either the ferric or ferrous valence state, depending largely upon the source of the iron in the synthesis gel. Thus, and FeO₂ tetrahedron in the structure can have a net charge of either -1 or -2. While it is believed that the Fe, Al and P framework constituents are present in tetrahedral coordination with oxygen (and are referred to herein as such), it is theoretically possible that some minor fraction of these framework constituents are present in coordination with five or six oxygen atoms. It is not, moreover, necessarily the case that all of the Fe, Al and/or P content of any given synthesized product is a part of the framework in the aforesaid types of coordination with oxygen. Some of each constituent may be merely occluded or in some as yet undetermined form, and may or may not be structurally significant. For convenience in describing the ferroaluminophosphates, the "short-hand" acronym "FAPO" is sometimes employed hereinafter. To identify the various structural species which make up the generic class FAPO, each species is assigned a number and is identified, for example, as FAPO-11, FAPO-31 and so forth. The term "essential empirical chemical composition" is meant to include the crystal framework and can include any organic templating agent present in the pore system, but does not include alkali metal or other ions which can be present by virtue of being contained in the reaction mixture or as a result of post-synthesis ion-exchange. Such ionic species, when present, function primarily as charge-balancing ions for FeO₂⁻ and/or AlO₂⁻² tetrahedra, FeO₂⁻² tetrahedra associated with PO₂⁺ tetrahedra or not associated with PO₂⁺ tetrahedra or an organic ion derived from the organic templating agent. In synthesizing the FAPO compositions, it is preferred to employ a reaction mixture composition expressed in terms of molar ratios as follows: aR : (Fe x Al y P z )O₂ : bH₂O wherein "R" is an organic templating agent; "a" has a value great enough to constitute an effective concentration of "R" and is within the range of >0 to 6; "b" has a value of from zero to 500, preferably 2 to 80; "x", "y", and "z" represent the mole fractions, respectively, of iron, aluminum and phosphorus in the (Fe x Al y P z )O₂ constituent, and each has a value of at least 0.01, and representing the following values for "x", "y", and "z": Point Mole Fraction x y z E 0.01 0.70 0.29 F 0.01 0.29 0.70 G 0.29 0.01 0.70 H 0.40 0.01 0.59 I 0.40 0.59 0.01 J 0.29 0.70 0.01 In the foregoing expression of the reaction composition, the reactants are normalized with respect to a total of (Fe + Al + P) = (x + y + z) = 1.00 mole. Iron can be introduced into the reaction system in any form which permits the formation in situ of reactive ferrous or ferric ions. Advantageously iron salts, oxides or hydroxides are employed such as iron sulfate, iron acetate, iron nitrate, or the like. Other sources such as a freshly precipitated iron oxide τ-FeOOH, are also suitable. TAPO MOLECULAR SIEVES TAPO molecular sieves are disclosed in U.S. Patent No. 4,500,561 and comprise a three-dimensional microporous crystal framework structure of [TiO₂], [AlO₂] and [PO₂] tetrahedral units which has a unit empirical formula on an anhydrous basis of: mR : (Ti x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the moles of "R" present per mole of (Ti x Al y P z )O₂ and has a value of between zero and about 5.0, the maximum value in each case depending upon the molecular dimensions of the templating agent and the available void volume of pore system of the particular titanium molecular sieve; "x", "y" and "z" represent the mole fractions of titanium, aluminum and phosphorus, respectively, present as tetrahedral oxides, representing the following values for "x", "y" and "z"; Point Mole Fraction x y z A 0.001 0.45 0.549 B 0.88 0.01 0.11 C 0.98 0.01 0.01 D 0.29 0.70 0.01 E 0.001 0.70 0.299 The parameters "x", "y" and "z" are preferably within the following values for "x", "y" and "z": Point Mole Fraction x y z a 0.002 0.499 0.499 b 0.20 0.40 0.40 c 0.20 0.50 0.30 d 0.10 0.60 0.30 e 0.002 0.60 0.398 The titanium-containing molecular sieves are referred to hereinafter, solely for point of reference herein as "TAPO" molecular sieves, or as "TAPOs" if the reference is to the class as a whole. This designation is simply made for the sake of convenient reference herein and is not meant to designate a particular structure for any given TAPO molecular sieve. The members of the class of TAPO's employed hereinafter in the examples will be characterized simply by referring to such members as TAPO-5, TAPO-11, etc, i.e., a particular species will be referred to as TAPO-n where "n" is a number specific to a given class member as its preparation is reported herein. This designation is an arbitrary one and is not intended to denote structural relationship to another material(s) which may also be characterized by a numbering system. The term "unit empirical formula" is used herein according to its common meaning to designate the simplest formula which gives the relative number of moles of titanium, aluminium and phosphorus which form the [TiO₂], [PO₂] and [AlO₂] tetrahedral unit within a titanium-containing molecular sieve and which forms the molecular framework of the TAPO composition(s). The unit empirical formula is given in terms of titanium, aluminium and phosphorus as shown in Formula (1), above, and does not include other compounds, cations or anions which may be present as a result of the preparation or the existence of other impurities or materials in the bulk composition not containing the aforementioned tetrahedral unit. The amount of template R is reported as part of the composition when the as-synthesized unit empirical formula is given, and water may also be reported unless such is defined as the anhydrous form. For convenience, coefficient "m" for template "R" is reported as a value that is normalized by dividing the number of moles of organic templating agent by the total moles of titanium, aluminium and phosphorus. The unit empirical formula for a TAPO may be given on an "as-synthesized" basis or may be given after an "as-synthesized" TAPO composition has been subjected to some post treatment process, e.g., calcination. The term "as-synthesized" herein shall be used to refer to the TAPO composition(s) formed as a result of the hydrothermal crystallization but before the TAPO composition has been subjected to post treatment to remove any volatile components present therein. The actual value of "m" for a post-treated TAPO will depend on several factors (including: the particular TAPO, template, severity of the post-treatment in terms of its ability to remove the template from the TAPO, the proposed application of the TAPO composition, and etc.) and the value for "m" can be within the range of values as defined for the as-synthesized TAPO compositions although such is generally less then the as-synthesized TAPO unless such post-treatment process adds template to the TAPO so treated. A TAPO composition which is in the calcined or other post-treatment form generally has an empirical formula represented by Formula (1), except that the value of "m" is generally less than about 0.02. Under sufficiently severe post-treatment conditions, e.g., roasting in air at high temperature for long periods (over 1 hr.), the value of "m" may be zero (0) or, in any event, the template, R, is undetectable by normal analytical procedures. The TAPOs are preferably formed from a reaction mixture having a mole fraction of alkali metal cation which is sufficiently low that it does not interfere with the formation of the TAPO composition. The TAPO compositions are generally formed from a reaction mixture containing reactive sources of TiO₂, Al₂O₃, and P₂O₅ and an organic templating agent, said reaction mixture comprising a composition expressed in terms of molar oxide ratios of: fR₂O : (Ti x Al y P z )O₂ : g H₂O wherein "R" is an organic templating agent; "f" has a value large enough to constitute an effective amount of "R", said effective amount being that amount which form said TAPO compositions; "g" has a value of from zero to 500; "x", "y" and "z" represent the mole fractions, respectively of titanium, aluminum and phosphorus in the (Ti x Al y P z )O₂ constituent, and each has a value of at least 0.001 and being within the following values for "x", "y" and "z": Point Mole Fraction x y z h 0.001 0.989 0.01 i 0.001 0.01 0.989 j 0.32 0.24 0.44 k 0.98 0.01 0.01 Although the TAPO compositions will form if higher concentrations of alkali metal cation are present, such reaction mixtures are not generally preferred. A reaction mixture, expressed in terms of molar oxide ratios, comprising the following bulk composition is preferred: oR₂O : wM₂O : (Ti x Al y P z )O₂ : nH₂O wherein "R" is an organic template; "o" has a value great enough to constitute an effective concentration of "R" and is preferably within the range of from greater than zero (0) to about 5.0; "M" is an alkali metal cation; "w" has a value of from zero to 2.5; "n" has a value between about zero (0) and about 500; "x", "y" and "z" represent the mole fractions, respectively, of titanium, aluminum and phosphorus in the (Ti x Al y P z )O₂ constituent, and each has a value of at least 0.001 and being within the following values for "x", "y" and "z": Point Mole Fraction x y z h 0.001 0.989 0.01 i 0.001 0.01 0.989 j 0.32 0.24 0.44 k 0.98 0.01 0.01 When the TAPOs are synthesized by this method the value of "m" in Formula (1) is generally above about 0.02. Though the presence of alkali metal cations is not preferred, when they are present in the reaction mixture it is preferred to first admix at least a portion (e.g., at least about 10 weight percent) of each of the aluminum and phosphorus sources in the substantial absence (e.g., preferably less than about 20 percent of the total weight of the aluminum source and phosphorus source) of the titanium source. This procedure avoids adding the phosphorus source to a basic reaction mixture containing the titanium source and aluminum source, (as was done in most of the published attempts to substitute isomorphously [PO₂] tetrahedra for [SiO₂] tetrahedra in zeolitic structures). Although the reaction mechanism is by no means clear at this time, the function of the tempolate may be to favor the incorporation of [PO₂] and [AlO₂] tetrahedra in the framework structures of the crystalline products with [TiO₂] tetrahedra isomorphously replacing [PO₂] tetrahedra. Alkali metal cations, if present in the reaction mixture, may facilitate the crystallization of certain TAPO phases, although the exact function of such cations, when present, in crystallization, if any, is not presently known. Alkali cations present in the reaction mixture generally appear in the formed TAPO composition, either as occluded (extraneous) cations and/or as structural cations balancing net negative charges at various sites in the crystal lattice. It should be understood that although the unit formula for the TAPOs does not specifically recite the presence of alkali cations they are not excluded in the same sense that hydrogen cations and/or hydroxyl groups are not specifically provided for in the traditional formulae for zeolitic aluminosilicates. Almost any reactive titanium source may be employed herein. The preferred reactive titanium sources include titanium alkoxides, water-soluble titanates and titanium chelates. Since the exact nature of the TAPO molecular sieves are not clearly understood at present, although all are believed to contain [TiO₂] tetrahedra in the three-dimensional microporous crystal framework structure, it is advantageous to characterize the TAPO molecular sieves by means of their chemical composition. This is due to the low level of titanium present in certain of the TAPO molecular sieves prepared to date which makes it difficult to ascertain the exact nature of the interaction between titanium, aluminium and phosphorus. As a result, although it is believed that titanium, [TiO₂], has substituted isomorphously for [AlO₂] or [PO₂] tetrahydra, it is appropriate to characterize certain TAPO compositions by reference to their chemical composition in terms of the mole ratios of oxides in the as-synthesized and anhydrous form as: vR : pTiO₂ : qAl₂O₃ : rP₂O₅ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "v" represents an effective amount of the organic templating agent to form said TAPO compositions and preferably has a value between and including zero and about 3.0; "p", "q" and "r" represent moles, respectively, of titanium, alumina and phosphorus pentoxide, based on said moles being such that they are within the following values for "p", "q" and "r": Point Mole Fraction x y z A 0.004 1.0 1.22 B 176 1.0 11.0 C 196 1.0 1.0 D 0.828 1.0 0.0143 E 0.003 1.0 0.427 The parameters "p", "q" and "r" are preferably within the following values for "p", "q" and "r": Point Mole Fraction x y z a 0.008 1.0 1.0 b 1.0 1.0 1.0 c 0.80 1.0 0.60 d 0.333 1.0 0.50 e 0.067 1.0 0.663 ELAPO MOLECULAR SIEVES "ELAPO" molecular sieves are a class of crystalline molecular sieves in which at least one element capable of forming a three-dimensional microporous framework forms crystal framework structures of AlO₂⁻, PO₂⁺ and MO₂ n tetrahedral oxide units wherein "MO₂ n " represents at least one different element (other than Al or P) present as tetrahedral oxide units "MO₂ n " with charge "n" where "n" may be -3, -2, -1, 0 or +1. The members of this novel class of molecular sieve compositions have crystal framework structures of AlO₂⁻, PO₂⁺ and MO₂ n tetrahedral units and have an empirical chemical composition on an anhydrous basis expressed by the formula: mR : (M x Al y P z )O₂ wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the molar amount of "R" present per mole of (M x Al y P z )O₂; "M" represents at least one element capable of forming framework tetrahedral oxides; and "x", "y" and "z" represent the mole fractions of "M", aluminum and phosphorus, respectively, present as tetrahedral oxides. "M" is at least one different (i.e., not aluminum, phosphorus or oxygen) element such that the molecular sieves contain at least one framework tetrahedral unit in addition to AlO₂⁻ and PO₂⁺. "M" is at least one element selected from the group consisting of arsenic, beryllium, boron, cobalt, chromium, gallium, germanium, iron, lithium, magnesium, manganese, titanium and zinc, subject to certain restrictions on the combinations of elements as will appear from the discussions of individual groups of ELAPOs below. ELAPOs and their preparation are disclosed in European Patent Application Serial No. 85104386.9, filed April 11, 1985 (EP Publication No. 0158976, published October 13, 1985) and 85104388.5, filed April 11, 1985 (EP Publication No. 158349, published October 16, 1985). The "ELAPO" molecular sieves further include numerous species disclosed in others of the aforementioned patents, and copending and commonly assigned applications, relating to non-zeolitic molecular sieves. The ELAPO molecular sieves are generally referred to herein by the acronym "ELAPO" to designate element(s) "M" in a framework of AlO₂⁻, PO₂⁺ and MO₂ n tetrahedral oxide units. Actual class members will be identified by replacing the "EL" of the acronym with the elements present as MO₂ n tetrahedral units. For example, "MgBeAPO" designates a molecular sieve comprised of AlO₂⁻, PO₂⁺, MgO₂⁺² and BeO₂⁻² tetrahedral units. To identify various structural species which make up each of the subgeneric classes, each species is assigned a number and is identified as "ELAPO-i" wherein "i" is an integer. The given species designation is not intended to denote a similarity in structure to any other species denominated by a similar identification system. The ELAPO molecular sieves comprise at least one additional element capable of forming framework tetrahedral oxide units (MO₂ n ) to form crystal framework structures with AlO₂⁻ and PO₂⁺ tetrahedral oxide units wherein "M" represents at least one elemnt capable of forming tetrahedral units "MO₂ n " where "n" is -3, -2, -1, 0 or +1 and is at least one element selected from the group consisting of arsenic, beryllium, boron, cobalt, chromium, gallium, germanium, iron, lithium, magnesium, manganese, titanium and zinc. The ELAPO molecular sieves have crystalline three-dimensional microporous framework structures of AlO₂⁻, PO₂⁺ and MO₂ n tetrahedral units and have an empirical chemical composition on an anhydrous basis expressed by the formula: mR : (M x Al y P z )O₂; wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the molar amount of "R" present per mole of (M x Al y P z )O₂ and has a value of zero to about 0.3; "M" represents at least one element capable of forming framework tetrahedral oxides where "M" is at least one element selected from the group consisting of arsenic, beryllium, boron, cobalt, chromium, gallium, germanium, iron, lithium, magnesium, manganese, titanium and zinc. The relative amounts of element(s) "M", aluminum and phosphorus are expressed by the empirical chemical formula (anhydrous): mR : (M x Al y P z )O₂ where "x", "y" and "z" represent the mole fractions of said "M", aluminum and phosphorus.

In synthesizing the BAPO compositions, it is preferred to employ a reaction mixture composition expressed in terms of the molar ratios as follows: aR : (B x Al y P z )O₂ : bH₂O wherein "R" is an organic templating agent; "a" is the amount of organic templating agent "R" and is an effective amount preferably within the range of greater than zero (0) to about 6, and most preferably not more than about 1.0; "b" has a value of from zero (0) to about 500, preferably between about 2 and about 300, desirably not greater than about 20, and most desirably not greater than about 10; and "x", "y" and "z" represent the mole fractions of boron, aluminum and phosphorus, respectively, and each has a value of at least 0.01.

The exact nature of the BAPO molecular sieves is not entirely understood at present, although all are believed to contain BO₂, AlO₂ and PO₂ tetrahedra in the three-dimensional microporous framework structure. The low level of boron present in some of the instant molecular sieves makes it difficult to ascertain the exact nature of the interactions among boron, aluminum and phosphorus. As a result, although it is believed that BO₂ tetrahedra are present in the three-dimensional microporous framework structure, it is appropriate to characterize certain BAPO compositions in terms of the molar ratios of oxides.

When "n" is -1 or +1, the mole fractions "x", "y" and "z" are generally defined as being within the limiting compositional values or points as follows: Point Mole Fraction x y z A 0.01 0.60 0.39 B 0.01 0.39 0.60 C 0.39 0.01 0.60 D 0.60 0.01 0.39 E 0.60 0.39 0.01 F 0.39 0.60 0.01 When "n" is 0, the mole fractions "x", "y" and "z" are generally defined as being within the limiting compositional values or points as follows: Point Mole Fraction x y z G 0.01 0.60 0.39 H 0.01 0.47 0.52 I 0.94 0.01 0.05 J 0.98 0.01 0.01 K 0.39 0.60 0.01 There are three preferred subclasses of the CAPO molecular sieves, depending upon whether the value of "n" is -1, 0 or +1 (i.e. whether the chromium has an oxidation number of 3, 4 or 5), it being understood that mixtures of such are permitted in a given CAPO.

As a result, although it is believed that CRO₂ tetrahedra are substituted isomorphously for AlO₂ or PO₂ tetrahedra, it is appropriate to characterize certain CAPO compositions by reference to their chemical compositions in terms of the mole ratios of oxides.

Since the exact nature of the LiAPO molecular sieves is not clearly understood at present, although all are believed to contain LiO₂ tetrahedra in the three-dimensional microporous crystal framework structure, it is advantageous to characterize the LiAPO molecular sieves by means of their chemical composition. This is due to the low level of lithium present in certain of the LiAPO molecular sieves prepared to date which makes it difficult to ascertain the exact nature of the interaction between lithium, aluminum and phosphorus. As a result, although it is believed that LiO₂ tetrahedra are substituted isomorphously for AlO₂ or PO₂ tetrahedra, it is appropriate to characterize certain LiAPO compositions by reference to their chemical composition in terms of the mole ratios of oxides.
