摘　　要：研究发现铵盐对水介质直接法合成硬脂酸铅反应具有显著的催化加速作用。以粒度不大于74μm的PbO为原料,在60℃由水介质直接法合成优质品硬脂酸铅时,添加硬脂酸投料量2%(质量分数)的铵盐可使反应时间从330min缩短为80min。It was found that the reaction of synthesis of lead stearate by direct method in aqueous medium could be accelerated markedly by ammonium salts. When using PbO with particle size not more than 74 μm as raw material, the reaction time for the synthesis of high quality product of lead stearate by direct method in aqueous medium under 60 ℃ could be shortened from 330 min to 80 min by adding ammonium salts with 2% by weight of stearic acid.
