硬脂酸钙制备

(1)硬脂酸钠溶液制备将硬脂酸溶于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)硬脂酸钙的合成将含量为1074kg/m3(10°Bé)的氯化钙溶液加入到上述制备的硬脂酸钠溶液中，于65℃左右进行复分解反应，产物硬脂酸钙以沉淀析出。然后经过滤、水洗、于90℃左右干燥，即得成品。

3.将5.60g(0.1mol)的氧化钙悬浮在300mL,55℃的热水中。然后将化学纯的51.3g的硬脂酸溶解在350mL，70℃的热水中，再加入0.75g二乙醇胺，搅拌使之乳化。将已制就的硬脂酸乳液在2h内逐渐加到氧化钙悬浮液中，并充分搅拌，将形成的白色不溶物即硬脂酸钙滤出，干燥，得到产品。

4.直接法　在装有搅拌器、温度计的反应锅中加入定量的硬脂酸和CaO，升温至熔化，在不断搅拌下缓慢加入催化剂H2O2，并抽真空，控制反应温度在140～150℃，反应1.5～2.0h。反应完成后，出料并冷却、粉碎即得产品。反应式如下：

5.复分解法　将硬脂酸溶于20倍质量的热水中，加入含量饱和的烧碱溶液，于75℃左右进行皂化反应，生成稀的硬脂酸钠溶液。再将含量为1074kg/m ³的氯化钙溶液加入到硬脂酸钠溶液中，于65℃左右进行复分解反应，产物硬脂酸钙以沉淀析出。然后经过滤、水洗、于90℃左右干燥，即得成品。反应式如下：
