The kinetics of the depolymerization of chitosan in dilute aqueous HCl solutions by nitrous acid were studied. The rate of depolymerization is independent of the molecular weight of chitosan, first order with respect to the concentrations of both nitrous acid and glucosamine moieties, not catalysed
The molecular size of chitosan can be precisely modified by depolymerization with nitrous acid. The stoichiometry and specificity of the reaction, together with the simplicity of the reaction kinetics, provide the basis for derivation of a theoretical expression that relates the number-average molec
