摘　　要：研究了硬脂酸和氧化镧在催化剂的作用下直接合成硬脂酸镧的方法,探讨了催化剂的用量、反应温度、反应时间等因素对制备反应的影响。本法在生产中不产生废水,工艺流程短,生产成本低。Direct synthesis of lanthanum stearate is studied under the reaction of stearic acid to La2O3 in the presence of catalyst.Effects of temperature,catalyst and reaction time on the quality of lanthanum stearate are discussed.This method has advantageous of shorter process,lower cost,no production of polluted water and higher yields.

关 键 词：硬脂酸镧 热稳定剂 直接法
