摘要
以虾壳为主要原料制得的天然高分子化合物甲壳素和壳聚糖 ,资源丰富 ,应用范围十分广阔。提出了以 3 5 %(质量分数 )氢氧化钠醇水溶液为反应介质 ,并加入相转移催化剂制备壳聚糖的新方法 ,讨论了一些因素对壳聚糖制备过程的影响。
Natural polymers, chitin and chitosan, obtained from shells of crab and shrimp has been widely used in various fields. A new method of preparing chitosan by using 35% sodium hydroxide in alcohol and mixed solution as the reaction medium and a phase transfer catalyst is descrbed. Some influencing factors are discussed.
