采用不同的羧甲基化和硫酸化方法分别制备了N-羧甲基-O-磺基壳聚糖、O-羧甲基-N-磺基壳聚糖、O-羧甲基壳聚糖硫酸盐、N-羧甲基壳聚糖-6-硫酸盐和N，O-羧甲基-N，O-磺基壳聚糖，并测定了它们的红外光谱和13 C-NMR谱。
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.
