硬脂酸钡制备

(1)硬脂酸钠的制备将硬脂酸加入反应釜，搅拌下用20倍(质量)的热水溶解，在80℃左右加入含量为1074kg/m3(10°Bé)的烧碱，生成稀的硬脂酸钠溶液。

(2)硬脂酸钡的制备在上述制备的硬脂酸钠溶液中加入含量为1074kg/m3(10°Bé)的氯化钡溶液，于70℃左右进行复分解反应，产物硬脂酸钡以沉淀析出。经过滤、水洗，再于100～110℃进行干燥，即得成品。

3.将48g氢氧化钡［Ba(OH)2·8H2O］悬浮在300mL水中,温度为23℃。再将95.3g硬脂酸于25℃溶解在400mL水中，并加入4g浓度为28%～29%的氨水，制成乳液。将硬脂酸乳液于1.5h内在充分搅拌下逐渐加到氢氧化钡悬浮液中，得到白色不溶产物后，滤出，干燥，即得到硬脂酸钡产品。
