Analysis of positions of substitution of O-carboxymethyl groups in partially O-carboxymethylated cellulose by the reductive-cleavage method.
A method is described for the analysis of positions of substitution of O-carboxylated groups in commercial samples of O-carboxymethylcellulose. Sequential permethylation of the polymer and reductive cleavage gives eight products, which are analyzed as their O-acetyl derivatives by gas-liquid chromatography.
