Optimal conditions for isotachophoretic separation of carboxymethyl-D-glucoses formed by acidic depolymerization of carboxymethylcellulose were found. 6-O-carboxymethyl-D-glucose, 2-O-carboxymethyl-D-glucose and 3-O-carboxymethyl-D-glucose were identified and determined in the reaction mixture after carboxymethylcellulose hydrolysis. Relative reactivity of hydroxy groups in the glucopyranose unit of cellulose decreased in the following order: O(6)H greater than O(2)H much greater than O(3)H. This was found to be in agreement with the data published by other authors.
