醋酸钙制备

1.由碳酸钙与乙酸反应而得。制备无水乙酸钙的方法：将精制的粉状碳酸钙加到水中，搅拌成悬浮液，分次加入少量冰醋酸。反应结束后，将滤液在水浴上浓缩，从粘稠状滤液中析出白色固体即无水乙酸钙。

2.将100g碳酸钙加至500～700mL水中，得到悬浮液。在搅拌下逐次少量加入110mL冰醋酸，有二氧化碳气体放出。反应完成后，过滤，滤液置水浴上浓缩至溶液变稠，自稠液中析出白色产物，即无水醋酸钙。若母液长时间放置，析出的固体为一水醋酸钙。

3.由碳酸钙与乙酸反应，经精制制得。也可以贝壳为原料，经清洗、粉碎、煅烧制成石灰乳，再经中和、过滤、浓缩、干燥得成品。

4.将碳酸钙（或氢氧化钙）加到20%的乙酸溶液中进行反应：

当二氧化碳不再逸出时，反应结束。再加入少量碳酸钙，并加热到80℃，静置使不溶物沉淀完全后滤去，滤液用80%的乙酸酸化至石蕊呈弱酸性反应，然后蒸发浓缩至浓浆状，冷却结晶，滤出结晶，并于60～70℃下干燥，即得成品。

导读：醋酸钙，别名乙酸钙，它是钙的乙酸盐，分子式为Ca(C2H3O2)2。无水乙酸钙的吸湿性非常好，因此常见的乙酸钙都以一水合（Ca(CH3COO)2.H2O，CAS [5743-26-0]）的形式存在。在肾脏疾病中，血液中磷酸浓度可能升高（高磷酸盐血）并导致一些关于骨的问题。在日常饮食中可以摄入...
