Sodium CMC
is Cellulose ether produced by reacting Cellulose
with caustic soda and monochloroacetic acid in
presence of alcohol under rigidly controlled conditions.
CASRN: 9004-32-4
CAS Name:
Cellulose, Carboxymethyl ether, Sodium
Structure of
cellulose
Cellulose
is a water-insoluble polymer of vegetable origin
such as wood (eucalyptus, poplar, pine) or cotton.
The cellulose molecule consists of a large
number of glucose anhydride rings linked in chain
formation. Each polymer chain consists of
100 to 6000 glucose anhydride units
Structure of
Sodium CMC
Chemical Reaction Process Description: Sodium Carboxymethyl Cellulose is generally
produced by the reaction of Monochloroacetic acid (or it’s Sodium Salt) with
alkali cellulose prepared by treating Pulp with caustic soda 50% aqueous
solution.
