壳聚糖
壳聚糖(Chitosan)
CAS: 9012-76-4
化学式: C6H11NO4X2
性质
含有阳离子型壳聚糖的粉末，易溶于水，且不包含甲醛。可以与毛角阮蛋白的氨基酸形成化学键结合，有良好的直毛固定效果。粉末通常呈现白色或淡黄色的片状粉体，可以使发色更均匀和自然。
制法
用4%～6%盐酸水溶液在常温下将甲壳浸泡4～12小时，之后摄取甲壳质，然后加入浓碱，在60～140℃反应8小时，最后经水洗得到产物。

壳聚糖 - 简介
壳聚糖是一种天然聚合物，其化学结构为由N-乙酰葡萄糖胺和D-葡萄糖组成的多糖。壳聚糖常见于海洋中的甲壳类动物的外骨骼及真菌的细胞壁中。
性质：
1、生物可降解性：壳聚糖可以被细菌和真菌等自然界中的微生物降解，使其对环境无污染。
2、高生物相容性：壳聚糖在生物体内具有较好的相容性，不会引发明显的免疫反应。
3、高黏度：壳聚糖溶液具有高黏度，可用作粘合剂或增稠剂。
用途：
环境保护：壳聚糖可用作废水处理剂、油水分离剂等，具有可降解性和去除重金属离子的能力。
制法：
1、从壳聚糖质源中提取：通过对甲壳动物的外骨骼进行水解、提取和纯化，得到壳聚糖。
2、酶法合成：利用酶作用将底物转化为壳聚糖。
3、化学合成：通过化学反应将合适的原料转化为壳聚糖。
安全信息：
1、壳聚糖一般认为是一种安全无毒的物质，但对于过敏体质者可能引发过敏反应。
2、在使用壳聚糖过程中，要注意避免吸入粉尘或接触到眼睛和皮肤。
3、在储存和搬运壳聚糖时，应保持干燥和远离火源。
