制备

1.将新鲜制备的硬脂酸钾2%水溶液，在充分搅拌下慢慢加到浓度为1.5%的三氯化铝水溶液中去。为了将所有的硬脂酸完全沉淀为二硬脂酸铝。三氯化铝的用量按摩尔量计算应为硬脂酸钾的两倍左右。在水浴上加热完成反应后，将得到的二硬脂酸铝沉淀(泥浆状或凝块)，用水洗至无氯离子存在(用硝酸银溶液检测)。将产品在五氧化二磷存在下完全干燥至恒重。得到的二硬脂酸铝产品中通常含有20%～30%的硬脂酸，可通过用无水溶剂的提取来纯化产品。用无水丙酮在0℃，多次提取产品中的游离硬脂肪酸。最终可得到近乎理论组成的碱式二硬脂酸铝。

2.以硬脂酸为原料，加热熔融，与氢氧化钠溶液进行皂化反应，然后与硫酸铝进行复分解反应，最后经洗涤、离心脱水、干燥制得。
