| titleOfInvention | Production of amorphous cellulose |
| abstract | PURPOSE: To produce an amorphous cellulose completely freed from any crystalline region, by dissolving activated cellulose by adding thereto a specified amide and LiCl, adding a large amount of a nonsolvent for cellulose and thereby precipitating and regenerating the cellulose from the solution. n CONSTITUTION: To cellulose are added one or more amides selected from the group consisting of N,N'-dimethylacetamide,1-methyl-2-pyrrolidinone,1,3-dimethyl-2-imidazolidinone and 1-methyl-2-piperidinone, and the mixture is boiled under reflux to obtain activated cellulose and, after adding 5W20wt%, based on the total weight, LiCl, the mixture is allowed to stand for 24hr to obtain a cellulose solution. Then, this cellulose solution is mixed with a large amount of a solvent which is a nonsolvent for cellulose and is miscible with the amide (e.g., methanol) to precipitate and regenerate the cellulose. In this way, an amorphous cellulose is obtained which has a crystallization degree ≤10%, an equibrium moisture content ≥80%, and a sugar inversion by cellulase ≥90%. n COPYRIGHT: (C)1984,JPO&Japio |
