Abstract

A benzene - ethanol - water mixture was investigated as the solvent medium in synthesizing carboxymethyl cellulose (CMC). The process of carboxymethylation was optimized to produce CMC with DS > I.0, solution viscosity about 1500 mpa·s, and with uniform distribution of substituents. It is possible to scale up this process by using a kneading machine.
