9005-35-0 - 简介

海藻酸钙是一种无色结晶性固体。它具有以下几个主要性质:

溶解性:海藻酸钙在水中可以溶解,形成胶体溶液。

酸碱性:海藻酸钙呈酸性溶液,在酸性条件下更加稳定。

螯合性:海藻酸钙可以与许多金属离子形成络合物。

工业用途:海藻酸钙可以作为添加剂用于制造瓷器、纸张、染料和石油等工业产品。

海藻酸钙的制备方法主要有两种:

化学法:通过将硫酸与海藻等天然材料反应,然后使用氢氧化钙进行沉淀和结晶得到。

生物法:利用海藻中的海藻酸进行提取,然后经过酶解、纯化和结晶等步骤得到海藻酸钙。
在处理海藻酸钙时,应避免吸入粉尘和接触皮肤和眼睛,以免引起不适。如有意外接触或误食,应立即就医。最后更新:2024-04-09 21:21:28
