Title: Method of manufacturing an oxide of yttrium and or the rare earth metals
IPC: C01F17/241
Filed: 1971-04-19
Abstract: 1335616 Mixed oxides of yttrium and the rare earth metals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [25 March 1970] 24848/71 Heading C1A [Also in Division C4] An oxide of at least one of the elements yttrium and the rare-earth metals is manufactured by a method which comprises the steps of dispersing and partially dissolving an oxysulphide of at least one of the said elements in a solvent comprising a sulphide and/or a polysulphide of one or more of the alkali metals and converting the oxysulphide in the melt thus formed into the desired oxide by means of oxidation for at least  hour at between 1000 and 1500C. The crystal size of the oxide is dependent on the solubility of the oxide crystals in the solvent and on the rate at which oxidation is carried out. The oxidation is preferably performed by admitting air to the melt. The sulphides and/or polysulphides of sodium and potassium are preferably used as solvents but since the sulphides and polysulphides are very hygroscopic it is advantageous to use sulphide and sulphur as a supplier for polysulphides. Also a sulphite may be used optionally in combination with sulphur. However sodium and/or potassium thiosulphate is preferred. The oxysulphide is then mixed with 10 to 300% by weight of the thiosulphate whereafter the mixture is brought to 1000 to 1500 C. at which the thiosulphate decomposes. Generally the oxysulphide is formed by heating compounds of one or more of the elements yttrium and the rare-earth metals and a compound of sulphur at between 300 and 1500 C., e.g. a mixture of a sulphite and sulphur, a mixture of a carbonate and sulphur or a thiosulphate. The method produces luminescent oxide having a composition defined by the formula A 2-x D x O 3  in which A represents elements yttrium and/or gadolinium and D represents at least one of the elements having an atomic number from 58 to 63 inclusive and from 65 to 70 inclusive and wherein 0À0002#x#0À2.

Adhesives.-Resins suitable for use in coating- compositions and plastics containing cellulose derivatives are made by subjecting the condensation product of toluene sulphonamide with formaldehyde or other aldehyde or other compound having a reactive methylene group, with or without a small proportion of urea, to the action of heat in the absence of water. The product, together with cellulose derivatives may be made into solutions or plastics containing suitable low, medium, or high boiling solvents, plasticizers, natural or synthetic resins, pigments and dyes; the solutions may be used as adhesives for making safety glass by securing sheets of glass to celluloid. The cellulose derivatives mentioned are the formate, acetate, propionate and butyrate, and methyl, ethyl and benzyl cellulose; the solvents acetone, alcohol, benzene, ethylene di-chloride, ethyl acetate, ethyl lactate, tetrachlorethane, benzyl alcohol and diacetone alcohol; the plasticizers diphenylol propane monomethyl xylene sulphonamide, o- or methyl toluene sulphonamide; and fire retarders such as brominated tricresyl phosphate or other brominated organic compounds may be added. Natural resins such as manilla, acaroid, pontianak, kauri, dammar, rosin and shellac; ester gum (glycerin ester of rosin); and synthetic resins such as the fusible and soluble phenol-formaldehyde, diphenylol propane-formaldehyde, and phenol-furfural resins preferably prepared with acid catalysts, may be used. In an example condensation is effected between equimolecular or other proportions of p-toluene sulphonamide. and formaldehyde (as solution or as paraformaldehyde) are heated under reflux at 150‹ C. for 16-20 hours with or without an acid or alkaline catalyst yielding a soft yellow resin. This resin is converted into a harder product according to the invention by distilling to remove the water from the product; it is then heated at 200-260‹ C. under reflux, some formaldehyde which splits off being returned to the resin. Paraformaldehyde may be added at this stage up to 15-20 per cent of molecular proportion, the heating being continued; finally the product is distilled at 100-150‹ C. for 15 minutes to one hour. In another example the same reagents are heated with the addition of a relatively small quantity of urea, the condensation product being separated from the water and heated at 160‹ C. without refluxing. An example of an adhesive containing the synthetic resin is cellulose acetate 20 parts, the toluene sulphonamide resin 25 parts. acetone 60 parts.

Abstract: 1425850 Desulphurizing hydrocarbons ATLANTIC RICHFIELD CO 29 May 1973 [30 June 1972] 25383/73 Heading C5E Hydrocarbon materials are treated to reduce their sulphur contents by preferentially oxidizing at least a portion of the sulphur with an oxidant selected from organic peroxides, organic hydroperoxides and organic peracids in the presence of a catalyst which has been prepared by treating metallic molybdenum with a peroxy compound in the presence of a C 1-4  saturated alcohol to solubilize at least a portion of the molybdenum, treating the oxidized sulphur-containing mixture to remove at least a portion of the sulphur from the hydrocarbon material. The feedstocks treated can be crude oil, atmospheric or vacuum residuals, cracking residues, tar sand oil, shale oil or coal oil. The catalyst can be prepared by treating molybdenum powder with t-butyl hydroperoxide in the presence of t-butyl alcohol and a mixture of C 10-15  glycols containing 4 to 6 hydroxyl groups, at least one of which hydroxyl groups is primary. The oxidation can be carried out in the presence of 15-1000 p.p.m. dissolved molybdenum and an oxidant concentration equivalent to 0À1-10 atoms of active oxygen per atom of sulphur. The oxidant can be an impure t-butyl hydroperoxide, obtained by oxidation of isobutane and containing t-butyl alcohol. Sulphur can be removed from the oxidized hydrocarbon material by treatment with a base, by heating, by solvent refining or by hydrodesulphurization. In examples the oxidation is carried out by heating under reflux a mixture of oil feed, catalyst solution, t-butyl hydroperoxide oxidant and either benzene or t-butyl alcohol as oxidation solvent; the oxidized material is stripped to remove the oxidation solvent and heated at 734-800 F. with a purge of hydrogen to remove sulphur.
