Description: PRODUCTION OF LIGNIN-CELLULOSE RESINS AND CARBOHYDRATES TECHNICAL FIELD Cellulose-containing plants are broken down by mixing with an alkali metal hydroxide then heated to 150 C to 220 C while agi¬ tating for 5 to 60 minutes thereby producing a broken down alkali metal cellulose-containing plant,polymer then mixed with an acid compound until the pH is 5 to 7 thereby producing a lignin-cellulose resinous product and a mixture of carbohydrates. DISCLOSURE OF THE INVENTION This invention relates to a novel and economical process to break down particles of cellulose-containing plants into lignin-cellu¬ lose resinous products, CO and carbohydrates. The carbohydrates are then broken down into ethanol by fermentation. In U.S. Patent Applica¬ tion No. 013,139, filed February 21, 1979, by David H. Blount, M.D., it illustrated the process to break down cellulose containing plants into water soluble polymers, but did not include the discovery of carbohy¬ drates being produced in the process. In the process of this invention the cellulose-containing plant such as wood, is broken down into water soluble alkali metal lignin- cellulose polymer, carbohydrates and sodium carbonate. The lignin- cellulose bond is not broken in most of the cases, but the molecules of cellulose are broken into CO and carbohydrates. The carbohydrates appear to be a mixture with glucose being the predominent carbohydrate. The alkali metal lignin-cellulose may be separated from the car¬ bohydrate by using an organic solvent such as ketones, alcohols and many other solvents. The carbohydrates produced by this process may be utilized to pro¬ duce ethanol by fermentation as a food for animals and humans, and may be further reacted with organic epoxides, mono and polysubstituted or¬ ganic compounds to produce new and useful products. The lignin-cellulose resinous product may be used as an adhesive such as in producing plywood, in laminates, as filler, etc. and may be further reacted with aldehydes, aminoplasts, phenoplasts, epoxides, ketones, fur- furyl alcohol, amines, isocyanates, polya ines, polyisocyanates, mono and polysubstituted organic compound such as polyhalides, monohalides, organic anhydrides, epihalohydrins, halohydrins and other organic com¬ pounds to produce useful resins which may be utilized as adhesives, as laminates, as coating agent, as molding agents, as foams. The lignin- cellulose resinous products are soluble in common organic solvents such as ketones, alcohols, glycols, organic esters, etc. Lignin-cellulose resinous products CO ? and carbohydrates are pro¬ duced by reacting the following components: component (a): A cellulose-containing plant. component (b): An alkali metal hydroxide. component (c): A salt producing compound. component (a) Any suitable cellulose-containing plant or the products of cellulose- containing plants which contain cellulose may be used in this invention.

Siefken in Justus Liebigs Annalen der Chemie, 562, pages 75 to 136. Solutions of distillation residues accumulating during the produc¬ tion of tolylene * diisocyanate, diphenyl methane diisocyanate or hexa- ethylene diisocyanate, in monomeric polyisocyanates or in organic sol¬ vents and mixtures thereof may be used in this process. Phosgenation products of condensates of aniline or anilines alkylsubstituted on the nucleus, with aldehydes or ketones, may be used in this invention. Organic polyhydroxyl compounds (polyols) may be used in this in¬ vention with polyisocyanates or may be first reacted with a polyiso- cyanate to produce • isocyanate-terminated polyurethane prepolymers and then also used in this invention. Reaction products of from 50 to 99 mols of aromatic diisocyanates with from 1 to 50 mols of conventional organic compounds with a molec¬ ular weight of, generally, from about 400 to about 10,000, which con¬ tain at least two hydrogen atoms capable of reacting with isocyanates, may also be used. While compounds which contain amino groups, thiol groups or carbσxyl groups may be used, it is preferred to use organic polyhydroxyl compounds, in particular, compounds which contain from 2 to 8 hydroxyl groups, especially those with a molecular weight of from about 800 to about 10,000 and preferably from about 1,000 to about 6,000, e.g., polyesters, polyethers, polythioethers, polyacetals, polycarbonates or polyester amides containing at least 2, generally from 2 to 8, but preferably from 2 to 4, hydroxyl groups, of the kind known for producing homogenous and cellular polyurethanes. The hydroxyl group containing polyesters may be, for example, re¬ action products of polyhydric alcohols, preferably dihydric alcohols, with the optional addition of trihydric alcohols, and polybasic, pre- ferably dibasic, carboxylic acids. Instead of the free polycarboxylic acids, the corresponding polycarboxylic acid anhydrides or corresponding polycarboxylic acid esters of lower alcohols or their mixtures may be used for preparing the polyesters. The polycarboxylic acid may be ali¬ phatic, cycloaliphatic, aromatic and/or heterocyclic and may be substi¬ tuted, e.g., with halogen atoms and may be unsaturated. Examples include: succinic acid, adipic acid, sebacic acid, suberic acid, azelaic acid, phthalic acid, phthalic acid anhydride, isophthalic acid, tetrahydro- phthalic acid anhydride, fcrimellitic acid, hexahydrophthalic acid anhy¬ dride, tetrachlorophthalic acid anhydride, endomethylene tetrahydrophth- alic acid anhydride, glutaric acid anhydride, fumaric acid, maleic acid, maleic acid anhydride, dimeric and trimeric fatty acids such as oleic acid, optionally mixed with monomeric fatty acids, dimethylterephthalate and bis-glycol terephthalate.

The polyesters may also contain a proportion of carboxyl end groups. Polyesters of lactones, such as £-caprolactone, or hydroxycarboxylic acids such asco-hydroxycaproic acid, may also be used. The polyethers with at least 2, generally from 2 to 8 and preferably 2 or 3, hydroxyl groups used according to the invention are known and may be prepared, e.g., by the polymerization of epoxides, e.g., ethylene oxide, propylene oxide, butylene oxide, tetrahydrofuran, styrene oxide or epichlorohydrin, each with itself, e.g., in the presence of BF_, or by addition of these epoxides, optionally as mixtures or successively, to starting components which contain reactive hydrogen atoms such as al¬ cohols or amines, e.g., water, ethylene glycol; propylene-1,3 or 1-2- glycol; trimethylolpropane; 4,4-dihydroxydiphenylpropane, aniline, ammonia, ethanolamine or ethylenediamine. Sucrose polyethers such as those described, e.g., in German Auslegeschriften Nos. 1,176,358 and 1,064,938, may also be used according to the invention. It is frequently preferred to use polyethers which contain Dredominantly primary OH groups, (up to 90% by weight, based on the total OH groups contained in the polyether). Polyethers modified with vinyl polymers such as those which may be obtained by polymerizing styrene or acrylonitrile in the presence of polyethers, (U. S. Patent Nos. 3,383,351; 3,304,273; 3,523,093 and 3,110,695; and German Patent No. 1,152,536) and polybutadienes which contain OH groups are also suit¬ able. By "polythioethers" are meant, in particular, the condensation products of thiodiglycol with itself and/or with other glycols, di- carboxylic acids, formaldehyde, aminocarboxylic acids or amino al¬ cohols. The products obtained are polythio-mixed ethers or polythio- ether ester amides, depending on the cocomponent. The polyacetals used may be, for example, the compounds which may be obtained from glycols, e.g., diethylene glycol, triethylene glycol, 4,4 T -dihydroxydiphenylm thylmethane, hexanediol, and formaldehyde. Polyacetals suitable for the invention may also be prepared by the poly¬ merization of cyclic acetals. The polycarbonates with hydroxyl groups used may be of the kind, e.g., which may be prepared by reacting diols, e.g., propane-1,3-diol; butane-l,4-diol; and/or hexane-l,6-diol or diethylene glycol; triethy¬ lene glycol or tetraethylene glycol, with diarylcarbonates, e.g., di- phenylcarbonates or phosgene. The polyester amides and polyamides include, e.g., the predomi¬ nantly linear condensates obtained from polyvalent saturated and un¬ saturated carboxylic acids or their anhydrides and polyvalent satu¬ rated and unsaturated amino alcohols, diamines, polyamines and mixtures thereof. Polyhydroxyl compounds which already contain urethane or urea groups, modified or unmodified natural polyols, e.g., castor oil, carbohydrates and starches, may also be used. Additional products of alkylene oxides with phenolfor aldehyde resins or with resin-formalde¬ hyde resins are also suitable for the purpose of the invention. Examples of these compounds which are to be used according to the invention have been described, e.g., inHigh Polymers, Volume XVI, "Polyurethanes, Chemistry and Technology", published by Saunders- Frisch Interscience Publishers, New York, London, Volume I, 1962, . pages 32 to 42 and pages 44 to 54 and Volume II, 1964, pages 5 to 6 and 198 to 199; and in Kunststoff-Handbuch, Volume VH Vieweg-Hochtlen, Carl-Hanser-Verlag, Munich, 1966, e.g., on pages 45 to 71. If the polyisocyanates or the prepolymer which contains NCO groups have a viscosity above 2000 cP at 25 C, it may be advantageous to re¬ duce the viscosity thereof by mixing it with a low-viscosity organic polyisocyanate and/or an inert blowing agent or solvent. Inorganic polyisocyanates and isocyanate-terminated polyurethane silicate prepolymers may also be used in this invention. When an aqueous solution of alkali metal cellulose polymer is being used to react with, or as a curing agent for, polyisocyanates, it is advantageous in certain cases to use catalysts such as tertiary amines, e.g., triethylamine, tributylamine, N-methyl-morpholine, N- ethyl-raorpholine, tetramethyl_πylenediamine, pentamethyldie-i_ylenei_ciamine, triethanolamine, triisoprophanolamine, organo-metallic compound, e.g., tin acetate, tin octoate, tin ethyl hexoate, dibutyl tin diacetate, di- butyl tin dilaurate and mixtures thereof. Other examples of catalysts which may be used according to the in¬ vention and details of their action are described in Kunststoff-Handbuch, Volume VII, published by Vieweg and Hochtlen, Carl-Hanser-Verlag, Munich, 1966, e.g., on pages 96 and 102. Sila-amines are suitable catalysts, e.g., 2,2-4-trimethyl-2-silamorpholine or 1,3-diethyl aminomethyl tetra- methyl disiloxane. Suitable catalysts are also tetraalkyl ammonium hydroxides, alkali phenolates, alkali metal hydroxides, alkali phenolates, alkali-alcoholates and hexahydrotriazines.

The organic halogen-containing components Eire, however, preferred in the polyurethane-cellulose and polyurethane-cellulose-silicate cellular solid products. In the production of aldehyde cellulose, amino-alde- hyde-cellulose and phenol-aldehyde-cellulose cellular solid products, phosphoric acid may be used to react with the alkali metal atoms, there¬ by producing an alkali metal hydrogen phosphate which may be .used as the flame-resistant compound. Alkali ' metal silicates may be used as flame- resistant compounds __ „„„_ _••- - '" Any suitable waτ_er-binding agent may be used in this invention such as hydraulic cement, burnt lime, gypsum and synthetic anhydrites.

There are many different kinds of cement which may be used; in general, any mixture of fine ground lime, alumina and silica that will set to a hard product by admixture of water which combines chemically with the other ingredients to form a hydrate may be used. Detailed de¬ scriptions of the many kinds of cement which react with sand and rocks to produce concrete may be found in "Encyclopedia of Chemically Techno¬ logy", Volume 4, Second Edition, Published by Kirk-Othmer, pages 684 to 710, as well as in other well known references in this field. DETAILED DESCRIPTION OF THE INVENTION The preferred process to produce lignin-cellulose, carbohydrates and carbon dioxide is to mix about 2 parts by weight of air-dried f ne particles of a cellulose-containing plant with 1 to 3 parts by weight of an alkali metal hydroxide which is at a temperature of 150° C to 220 c while agitating for 5 to 60 minutes, thereby producing a water soluble broken down alkali metal cellulose-containing plant polymer, then a salt forming compound is mixed with the broken down alkali metal cellulose-containing plant polymer in an amount wherein the acid radical are about equal to or greater than the alkali metal radicals thereby producing a mixture of lignin-cellulose resinous product, CO , carbohydrates and salt; water is then added to the mixture until a solution is produced that contains 20% to 70% solids. .The pH is then adjusted to a pH of 5 to 6.5 and the lignin-cellulose resinous product floats to the top and is separated from the aqueous solution of carbohydrates by filtration or decantation.

The resultant foam may optionally ontain foam stabilizers such as surfactants, foam formers, emulsifiers and, if desired, other organic or inorganic fillers or diluents may ini¬ tially be converted by blowing gas into a foam and the resulting foam subsequently mixed in a mixer with the other components, the resulting mixture being allowed to harden. Instead of blowing agents, it is also possible to use inorganic or organic, finely divided hollow bodies such as expanded hollow beads of glass, plastic, straw, expanded clay, and the like, for producing foams. The foams obtainable in this way can be used either in their dry or their moist form if desired after a compacting or tempering process, optionally carried out under pressure, as insulating materials, cavity fillings, packaging materials, building materials, etc. They can also be used in the form of sandwich elements, for example, with metal- covering layers, in house, vehicle and aircraft construction. It is also possible to introduce into the foaming reaction mixtures, providing they are still free-flowing, organic and/or organic foamable or already foamed particles, for example, expanded clay, expanded glass, wood, popcorn, cork, hollow beads of plastics, for example, vinyl chlo¬ ride polymers, polyethylene, styrene polymers or foam particles thereof or even, for example, polysulphone, polyepoxide, polyurethane, ureafor- maldehyde, phenol formaldehyde, polyimide polymers, urea-silicate- formaldehyde polymers, phenol-silicate-formaldehyde, epoxy silicate polymers, polyisocyanate silicate polymers, polyurethane silicate poly¬ mers or the reaction mixture may be allowed to foam through interstitial spaced particles in packed volumes of these particles and, in this way, to produce insulating materials. Combinations of expanded clay, glass or slate with the reaction mixture, according to the invention, are especially preferred. It is also possible to introduce into the foaming reaction mixtures, providing they are still free-flowing, at a pre-determined temperature, a blowing agent which is capable of evaporation or of gas formation at these temperatures, for example, a halogenated hydrocarbon. The ini¬ tial liquid mixture formed can be used not only for producing uniform foams or non-uniform foams containing foamed or unfoamed fillers, but it can also be used to foam through any given webs, woven fabrics, lattices, structural elements or other permeable structures of foamed materials, resulting in the formation of composite foams with special properties, for example, favorable flame behavior, which may optionally be directly used as structural elements in the building, furniture or vehicle and aircraft industries. The cellular solid products (foams) according to the invention can be added to soil in the form of crumbs, optionally in admixtures with fertilizers and plant-protection agents, in order to improve its agrarian consistency. Since the hardened foams obtained by the process according to the invention can show considerable porosity after drying, they are suitable for use as drying agents because they can absorb water; however, they can also be charged with active substances or used as catalyst supports or filters and absorbents. On the other hand, the foams can be subsequently lacquered, metallized, coated, laminated, galvanized, subjected to vapor deposi¬ tion, bonded or flocked in either their moist or dry form or in im¬ pregnated form. The moldings can be further processed in their moist or dried form, for example, by sawing, milling, drilling, planing, polishing and other machining techniques. The optionally filled molding can be further modified in their properties by ther¬ mal after-treatment, oxidation processes, hot-pressing, sintering pro¬ cesses or surface melting or other consolidation processes. Suitable mold materials include inorganic and/or organic foamed or unfoamed materials such as metals, for example, iron, nickel, fine steel, lac¬ quered or, for example, teflon-coated aluminum, porcelain, glass, wood, plastics such as PVC, polyethylene, epoxide resins, ABS, polycarbonate, etc. Fillers in the form of particulate or powdered materials can be additionally incorporated into the liquid mixtures of the foamable reactants for a number of applications. Suitable fillers include solid inorganic or organic substances, for example, in the form of powders, granulate, wire, fibers, dumb bells, crystallites, spirals, rods, beads, hollow beads, foam particles, webs, pieces of woven fabric, knit fabrics, ribbons, pieces of film, etc., for example, of dolomite, chalk, alumina, asbestos, basic silicas, sand, talcum, iron oxide, aluminum oxide and oxide hydrate, zeolites, calcium silicates, basalt wool or powder, glass fibers, C-fibers, .graphite, carbon black, A1-, Fe-, Cu-, Ag-powder, molybdenum sulphite, steel wool, bronze or copper cloth, silicon powder, expanded clay par¬ ticles, hollow glass beads, glass powder, lava and pumice particles, wood chips, sawdust, cork, cotton, straw, jute, sisal, hemp, flax, rayon, popcorn, coke, particles of filled or unfilled, foamed or unfoamed, stretched or unstretched, organic polymers including plastics and rubber waste. Of the number of suitable organic polymers, the following, which can be present, for example, in the form of powders, granulate, foam particles, beads, hollow beads, foamable or unfoamed particles, fibers, ribbons, woven fabrics, webs, etc., are mentioned purely by way of examples: polystyrene, polyethylene, polypropylene, polyacrylo- nitrile, polybutadiene, polyisoprene, polytetrafluoroethylene, aliphatic and aromatic polyesters, melamine-urea or phenol resins, polyacetal re¬ sins, polyepoxides, polyhydantoins, polyurea, polyethers, polyurethanes, polyimides, polyamides, polysulphones, polycarbonates, and, of course, any copolymers as well. Inorganic fillers are preferred. Generally, the composite materials according to the invention can be. filled with considerable quantities of fillers without losing their valuable property spectrum. The amount of fillers can exceed the amount of the reactants. In special cases, the foamed products of the present invention act as a binder for such fillers. Basically, the production of the cellular solid products according to the invention is carried out by mixing the reactants in one or more stages in a continuously- or intermittently-operated mixing apparatus and then allowing the resulting mixture to foam and solidify, usually outside the mixing apparatus in molds, or on suitable materials. The reaction temperature required for this, which may be from 0 C to 200° C and preferably from 20° C to 160 C, may either be achieved by heating one or more of the reactants before the mixing process or by heating the mixing apparatus itself or, alternatively, by heating the reaction mixture after the components have been mixed. Combina¬ tions of these or other methods of adjusting the reaction temperature may, of course, also be employed. In most cases, sufficient heat is evolved during the reaction to enable the reaction temperature to rise to values above 50 C after the reaction or foaming has begun. In particular, however, the process according to the invention is suitable for in situ foaming on the building site. Any hollow forms obtained by means of shuttering in the conventional way may be filled up and used for foaming in this way. The lignin-cellulose resinous product as produced in this invention may be pre-reacted with an amino compound and an aldehyde, at a pH of 7 to 12, to produce a liσuid alkali cellulose-amino-aldehyde, then placed in a mixing chamber, optionally adding a blowing agent, emulsi- fier, foam stabilizer, filler, flame-retardant and other additives, then rapidly mixed with an acid compound and then pumped or blown by compressed air into a mold such as a wall, ceiling, etc., while ex¬ panding, thereby producing a cellular solid product, useful for sound and thermal insulation. The foaming components may also be pumped into a large mold to expand and harden into a cellular product. The cellular product may be sawed into slabs and used for insulation in houses, boats, vehicles, airplanes, etc. The cellular product may also be chopped by a suitable machine into particles and poured or blown "5U E4 __ O PI_ Λ, ~ Ϊpδ~ . **Uτ\* into places such as ceilings, walls, etc., and used for thermal and sound insulation. The cellular product may also be used as a molding powder and molded into useful products by heat and pressure in a mold. The lignin-cellulose resinous product as produced in this invention may be pre-reacted with a phenol compound and an aldehyde, at a pH of 7 to 12, to produce a liquid polymer. This liquid polymer may be foamed in the same manner as the amino-aldehyde-lignin-cellulose poly¬ mers and may be used for the same purposes, sound and thermal insula¬ tion, molding powder and in the production of pains, varnishes, adhesives, etc. The liquid phenoplast lignin-cellulose polymer may be poured into a mold, then heated for 1 to 6 hours, thereby producing a tough, solid, .useful product. The alkali cellulose polymer as produced in this invention may be pre-reacted with a phenol compound, an amino and an aldehyde compound at a pH of 7 to 12, to produce a liσuid resin. This liquid resin may be poured into a mold, then heated to 70 C to 100 C for 1 to 6 hours, thereby producing a tough, solid, useful product. This liquid resin may also be foamed on the job by adding the liquid resin and an acid compound (catalyst) simultaneously to a mixing chamber, then rapidly pumping or using air pressure to transfer the foaming mixture into a mold such as walls, ceilings, etc., where it rapidly sets within a few seconds to several minutes into a tough, rigid, somewhat elastic, cellular solid product, optionally containing blowing agent, emulsifier, foam stabilizer, filler, flame-retardant agents and other additives. The product has good sound and thermal qualities, good flame-retardant properties and good dimensional stability. The phenoplast-lignin- cellulose-aminoplast resins may be used as molding powder and molded by heat and pressure into useful objects. The phenoplast-lignin-cellu- lose-aminoplast resin may be foamed into large slabs, then sawed into various sizes and thicknesses or broken into small particles and used for thermal and sound insulation in houses, buildings, vehicles and aircrafts; these large slabs of foam may be sawed into various thick¬ nesses and widths, then a moisture barrier such as aluminum foil may be applied by the use of an adhesive to produce an insulation material that has excellent flame- esistant properties, good strength and ex¬ cellent thermal- and sound-insulation qualities. The process according to the invention to produce the polyisocya¬ nate lignin-cellulose foam, polyurethane lignin cellulose foam and poly- urethane-silicate-lignin-cellulose foam is particularly suitable, however, for in situ foaming on the building site. Any hollow molds normally produced by shuttering in forms can be obtained by casting and foaming. The reaction mixture, -optionally containing a blowing agent, emulsifier, foam stabilizer, filler, flame-retardant agent, diluents, deodorants, coloring agents and other agents, produced by adding the components simul¬ taneously to a mixing apparatus, is immediately pumped or sprayed by compressed air into a mold, e.g., walls, ceilings, cold or heated relief molds, solid molds, hollow-molds, etc., where it may be left to harden. The foaming reaction mixture may also be forced, cast or injection molded into cold or heated molds, then hardened, optionally under pressure and at room temperature or at temperatures up to 200 C, optionally using a centrifugal casting process. At this stage, reinforcing elements in the form of inorganic and/or organic or metal wires, fibers, non-woven webs, foams, fabrics, supporting structures, etc., may be incorporated in the foaming mixture. This may be achieved, for example, by the fibrous-web-impregnation process or by processes in which the reaction mixtures and reinforcing fibers are together applied to the mold, for example, by means of a spray apparatus. The molded products obtainable in this way may be used as building elements, e^g., in the form of option¬ ally foamed sandtich elements which may be used directly or subsequently laminated with metal, glass, plastics, etc. The fire characteristics of the material are good, but are improved by the addition of flame- retardant agents and also by the addition of the oxidated silicon com¬ pounds. On the other hand, the products may be used as hollow bodies, e.g., as containers for goods which are required to be kept moist or cool, or they may be used as filter materials or exchangers, as cata¬ lyst carriers or carrier of other active substances, as decoration elements, shock-resistant packaging, furniture components and cavity fillings. They may also be used in production of molds for metal casting and in model building. The cellular products may also be prod¬ uced by pouring the components into a mold, then mixing well, after which the mixture expands, then hardens in the mold. The mold may be in the form of a large slab so that it can be sawed into various sizes, shapes and thicknesses as desired. The reaction mixtures may also be ^ E_4_ OMPI IPC _V i?tfATl-^ foamed up and hardened while the form of droplets or may be dispersed, e.g., in petroleum hydrocarbons or while they are under condition of free fall. Foam beads are obtained in this way. The foamed products produced by these methods may also be added in a crumbly form to soil, optionally with the addition of fertilizers and plant-protective agents so as to improve the agricultural consistency of the soil. Foams which have ahigh water content may be used as substrates for the propagation of seedlings, shoots and plants or for cut flowers. The mixtures may be sprayed on terrain which is impassible or too loose, such as dunes or marshes, to strengthen such terrain so that it will be firm enough to walk on within a short time, and will be protected against erosion. The foaming mixtures may also be used underground in caves, mines, tunnels, etc., by spraying the foaming mixture onto wire mesh, fiber¬ glass cloth, woven fabrics or directly on the walls, to produce pro¬ tective layers to prvent accidents. It is also possible to introduce into the roaming reaction mixtures, providing they" are still free-flowing, organic and/or organic foamable or already foamed particles such as expanded clay, expanded glass, wood, popcorn, cork, hollow beads of plastics, for example, vinyl chloride polymers, polyethylene, styrene polymers or foam particles thereof or even, for example, polysulphone, polyepoxide, polyurethane, ureaformalde- hyde phenol formaldehyde, polyimide polymers, or to allow the reaction mixtures to foam through interstitial space in packed volumes of these particles, and in this way to produce insulating materials which are distinguished by excellent flame behavior. Combinations of expanded clay, glass, or slate with the reaction mixtures, according to the inven¬ tion,-are especially preferred. The lignin-cellulose resinous product, poly(aldehyde lignin-cellu¬ lose) resinous product, poly(aminoplast-lignin-cellulose) resinous pro¬ duct, poly(phenoplast lignin-cellulose) and poly(aminoplast-lignin-cellu- lose phenoplast) resinous produced may use as a thermosetting resinous adhesive useful particularly as plywood for lumbar laminating adhesive. The adhesive may be cured by heat (250° C to 300° C) and pressure (110 to 260 psi). The adhesive resinous products will also cure by the pre¬ sence of an alkali or acetic catalyst or by using hexamethylene or para¬ formaldehyde. These poly(polyisocyanate-lignin-cellulose) polyurethane lignin cellulose, polyurethane lignin-cellulose silicate and poly(polyiso¬ cyanate lignin-cellulose silicate) cellular products are soluble in organic solvents and may be utilized as paints, varnishes, adhesives, fillers, caulking material, etc. The object of the present invention is to provide a novel process to produce lignin-cellulose resinous products, carbohydrates and C0„ from cellulose-containing plants. Another object is to produce novel lignin-cellulose resinous products which are highly reactive. Still another object is to product carbohydrates which can be fermented to produce ethanol.

Another object is to produce lignin-cellulose polymers that will react with polyurethane prepolymers and oxidated silicon compounds to produce novel poly(urethane-lignin-cellulose- silicate) resins and cellular solid products.

Parts and percentages are by weight unless otherwise indicated. Example 1 About 1 part by weight of lye flakes (NaOH) and 2 parts by weight of fir sawdust are mixed then heated to 150 to 220 C while agitating at ambient pressure, with care being taken for the mixture not to burn, for 5 to 60 minutes or until the mixture softens and expands into a dark-brown, thick liquid when hot. It cools to a solid, thereby pro¬ ducing a water soluble broken-down alkali metal cellulose containing plant polymer; the dilute sulfuric acid is added until the pH is 5 to 6.5 while agitating thereby producing a dark brown lignin-cellulose resinous product which floats to the top, C0_ is given off, salt and an aqueous solution of carbohydrates. The lignin-cellulose resinous product is recovered by filtration, then ground into a powder, washed with water to remove any salt, then dried. The lignin-cellulose resinous product ssoofftteenn aatt aabbooiut 120 C and may be molded into useful products by heat and pressure. Example 2 About equal parts by weight of dry pine sawdust is added to sodium hydroxide flakes which are at about 150 to 220 C while agitating, the mixture expands into a dark-brown, thick liσuid which solidifies on cooling thereby producing broken down alkali metal cellulose-containing plant polymer. The polymer is added to water to make an aqueous solu¬ tion containing 50% solids. About 90% of the original sawdust is soluble in water.
