摘 要:Five kinds of carboxymethyl sulfochitosans with different regions such as N-carboxymethyl-O-sulfochitosan, O-carboxymethyl-N-sulfochitosan, O-carboxymethyl chitosan sulfate, N-carboxymethyl chitosan-6-sulfate, and N,O-carboxymethyl -N,O-sulfochitosan were prepared respectively by using differential carboxymethylation and sulfation methods, and their IR spectrum and 13C-NMR spectrum were measured.
