MICROCRYSTALLINE CELLULOSE PRODUCTION PROCESS

摘要

paper-and- pulp industry. SUBSTANCE: microcrystalline cellulose is fabricated by treatment of fibrous cotton-cleaning and temperature industry wastes on heating to 80 C for 1 h with mixture of 3.5% hydrochloric acid and 0.6% nitric acid in presence of 10% phosphorus-molybdenum acid as catalyst at liquid modulus 1:10 followed by washing and drying. EFFECT: simplified technology and enabled high yield of product, homogeneous with respect to its molecular weight and with degree of polymerization 130-190. 1 tbl
