METHOD FOR PRODUCTION OF HIGH QUALITY NITROCELLULOSE OF COTTON LINTER

FIELD: production of nitrocellulose. SUBSTANCE: cotton linter is nitrated and then it is treated by 0.2-1.6 % aqueous solution of oxidant, the process is carried out at temperature not higher 100 C. Thus prepared nitrocellulose is autoclaved, the process takes place in water at temperature higher 10...

description	FIELD: production of nitrocellulose. SUBSTANCE: cotton linter is nitrated and then it is treated by 0.2-1.6 % aqueous solution of oxidant, the process is carried out at temperature not higher 100 C. Thus prepared nitrocellulose is autoclaved, the process takes place in water at temperature higher 100 C or in 0.51-0.79 % aqueous solution of nitric acid. Then nitrocellulose is treated with 0.1-1.6 % aqueous solution of hydrogen peroxide, the process is carried out at pH not more 10 and at temperature not higher 100 C. Solubility of nitrocellulose is increased up to 100 %. EFFECT: improved efficiency of the method. 3 cl, 3 tblw
