Carboxyl Methyl Cellulose Details
Carboxy methyl cellulose (CMC) or cellulose gum is a cellulose
derivative with carboxymethyl groups (-CH2-COOH) bound to some of
the hydroxyl groups of the glucopyranose monomers that make up
the cellulose backbone. It is often used as its sodium salt,
Sodium Carboxymethyl Cellulose.
It is synthesized by the alkali-catalyzed reaction of cellulose
with chloroacetic acid. The polar (organic acid) carboxyl groups
render the cellulose soluble and chemically reactive. The
functional properties of CMC depend on the degree of substitution
of the cellulose structure (i.e., how many of the hydroxyl groups
have taken part in the substitution reaction), as well as the
chain length of the cellulose backbone structure and the degree
of clustering of the carboxymethyl substituents.
