A simple non-aqueous method for carboxymethylation of galactomannans.
TLDR
In this paper, a simple nonaqueous method for the preparation of carboxymethyl derivatives of galactomannans and other biopolymers has been developed, where guar, tara and locust bean gums were subjected to carboxylmethylation using monochloroacetic acid under the catalytic influence of NaHCO3 in dry state.About:
