制备

(1)硬脂酸钠溶液制备将硬脂酸溶解于20倍(质量)的热水中，加入含量为1074kg/m3(10°Bé)的烧碱溶液，于75℃左右进行皂化反应，生成稀的硬脂酸钠溶液。

(2)硫酸镉溶液制备将金属镉溶解于硫酸和硝酸中，制得硫酸镉溶液。

(3)硬脂酸镉的制备将硫酸镉溶液加入到硬脂酸钠溶液中，于55℃左右进行复分解反应，产物硬脂酸镉以沉淀析出。经过滤、水洗，于70～75℃下干燥，即得成品。

4.将等摩尔量的硬脂酸和醋酸镉粉末混匀后，在117～118℃下加热，蒸出乙酸和结晶水后，就得到定量的硬脂酸镉。本反应也可在过量的乙酸溶液中进行。

5.将15g硬脂酸钠溶在1L热水中，得到清澈的溶液，趁热将此溶液加入过量的1％氯化镉或硫酸镉的溶液中，一边加一边强力搅拌，待析出絮状的硬脂酸镉沉淀后，用倾泻法彻底洗涤，直到无游离的可溶性镉盐存在为止。置空气浴中在115～120℃下干燥10～12h。冷却后得到硬脂酸镉产品，粉碎后置密封瓶中保存。
