摘 要: 应用微波辐射技术,用50%NaOH溶液对甲壳素进行脱乙酰基制备壳聚糖.实验表明:甲壳素经微波一次碱处理15min脱乙酰度达774%,经第2次微波碱处理脱乙酰度可达90%以上,经3次以上微波碱处理脱乙酰度几乎接近100%. Using microwave radiation technology,the chitosan is prepared by chitin deacetylation in about 50% sodium hydroxide solution.The experiments show that the deacetylation is 77% once in fifteen minutes.It almost reaches 100% deacetylation by three times and over.
