摘　　要：通过采用新型的催化剂(氨水溶液)代替传统用的催化剂(醋酸或醋酸锌)用于二烷基二硫代磷酸锌的制备,所制得的产品的pH值明显比使用传统的催化剂时要高,并且其它的性能指标也能达到相关的标准和要求。新型的催化剂优于传统的催化剂。A new catalyst （ammonia） was used to the preparation of zinc salt of dialkyl dithiophosphate instead of the traditional ones （acetic acid or zinc of acetic acid）. Obviously the pH values of the prepared products were higher than those with the traditional catalyst and the performance indexes of the products had reached the relating standards and specifications. The new catalyst is superior to the traditional ones.
