Abstract
The distribution of N-acetyl group in partially deacetylated chitin (DA-chitin) was investigated by nitrous acid deamination. Most deamination products of various DA-chitins (over 50% of deacetylation), prepared under homogeneous conditions, were oligomers of less than six units. These results would suggest a random distribution of N-acetyl groups in the DA-chitin molecule.
摘要
通过亚硝酸脱氨反应研究了部分脱乙酰化壳聚糖（DA-壳聚糖）中N-乙酰基的分布情况。在均相条件下制备的各种DA-壳聚糖（脱乙酰度超过50%）的大多数脱氨产物是少于六个单元的低聚物。这些结果表明DA-壳聚糖分子中N-乙酰基呈随机分布。
