Carboxyl Methyl Cellulose
Introduction
Natural cellulose is one of the most widely distributed and abundant polysaccharides in nature.At present, the modification technology of cellulose mainly focuses on etherification and esterification.Carboxymethylation is one of the etherification techniques.Cellulose after carboxymethylation carboxymethyl cellulose (CMC), its aqueous solution has thickening, film formation, adhesion, water retention, colloidal protection, emulsification and suspension, widely used in petroleum, food, medicine, textile and paper industry, is one of the most important cellulose ether.
