【摘要】 研究了在中国鲎壳中分离出甲壳素 ,得出最佳工艺条件为 :先用 1 mol/L盐酸浸泡鲎壳 ,水洗至中性后用 2 mol/L的氢氧化钠溶液浸泡 ,再用 1 mol/L的盐酸浸泡 ,最后在 80°C下与 2 mol/L的氢氧化钠溶液反应 3h;产率为 30 %。用红外光谱和 X-衍射对产物进行了表征。保湿和吸湿实验表明中国鲎甲壳素有较好的保湿和吸湿性能更多还原

【Abstract】 Chitin was isolated from tachypleus tridentatus and its best technological condition was worked out. The tachypleus tridentatus shell was flushed soaked with 1 mol/L hydrochloric acid with water untill neutral. Then it was soaked with 2 mol/L sodium and hydroxide 1 mol/L hydrochloric acid, finally reacted for 3 hours with 2 mol/L sodium hydroxide at 80 °C . Yield was 30%, characterized by IR and X ray. It showed that this tachypleus tridentatus chitin was better in hygroscopicity and moisture retention.更多还原
