HETEROGENEOUS ACID HYDROLYSIS OF CHITIN AND CHITOSAN FROM MARINE CRUSTACEANS
Kinetic curves of chitin and chitosan deacetylation are given in various acids. Influence of the acids' degree of ionization and acid residues' nucleophilicity on the kinetics of deacetylation and glycosidic linkage cleavage of chitin with different initial degree of deacetylation was shown. It was assumed control of the degree of deacetylation and molecular mass of chitin/chitosan when using acids with different nucleophilicity and degree of ionization, respectively.
