| 摘 要： | 有关甲壳素的乙酰化已有报导[1-3],但报导的各种方法在产品性能等方面尚存在不少问题。本文报导在对甲苯磺酸或高氯酸-对甲苯磺酸催化下进行甲壳素乙酰化的新方法;同时,对用单一高氯酸催化的反应作了进一步研究,从而制得了高取代度及较高比浓粘度的乙酰化甲壳素产物。

| Abstract: | Acetylation of chitin with acetic anhydride was investigated using p-toluene sulfonic acid,perchloric acid or a mixture of p-toluene sulfonic acid and perchloric acid as catalyst.It was found that with these methods products having high degrees of acetylation and good solubility in formic acid could be obtained. |
