Title: Improvements in the production of cellulose ethers
IPC: C08B11/02
Filed: 1941-09-11
Abstract: 551,893. Cellulose ethers ; alkali cellulose. GROOMBRIDGE, W. H., and DOWNING, J. Sept. 11, 1941, No. 11639. [Class 2 (ii)] Cellulose material is subjected to an etherification process wherein the cellulose is impregnated with a solution of an alkali which is then concentrated on the cellulose by azeotropic distillation, impregnation and concentration being carried out to produce an alkali cellulose containing up to about 2.5 mols. of alkali for each glucose unit of the cellulose, and which is either anhydrous or contains alkali and water in a ratio of at least 2 molecules of alkali to 3 of water. The alkali cellulose is then etherified with an amount of etherifying agent just, or slightly less than, chemically equivalent to the alkali. Further amounts of alkali and etherifying agent in about chemically equivalent proportions are introduced during etherification, the amounts added being so regulated that the original relative proportion limits of the alkali, cellulose, and etherifying agent are adhered to throughout the reaction. The alkali and etherifying agent may be introduced in a number of stages, each addition being made only when the reagent present in the etherification mixture is substantially exhausted, or the alkali and etherifying agent may be continuously introduced throughout the reaction. Etherification may be continued until an ether which is soluble in organic solvents is produced. The alkali may be caustic soda or potash. For the concentration of the alkali solution an azeotroping liquid which is suitable as an inert medium in the subsequent etherification may be used, e.g. benzene or xylene, or toluene. When using diethyl sulphate as the etherifying agent, and an inert diluent such as toluene, the reaction may be carried out at a temperature of 100-120‹C. Production of the alkalicellulose and of the cellulose ether may be effected in an inert atmosphere, e.g. nitrogen.
