摘要
The distribution of functional groups in a monomeric unit of carboxymethyl dextran was studied by H-1 NMR. The distribution of carboxymethyl groups between the 2-, 3-, and 4-positions of the glucopyranose unit of dextran was studied as a function of the total degree of substitution. The activity constants were determined for hydroxyls in 2-, 3-, and 4-positions of the unit in carboxymethylation reaction.
