摘　　要：研究了清净剂烷基水杨酸钙(T109)的水解安定性,分析了单剂在水存在的条件下,搅拌时间、搅拌速度、环境温度及含水量等因素对烷基水杨酸钙水解安定性的影响。结果表明:搅拌时间、搅拌速度、环境温度和含水量等因素对烷基水杨酸钙的水解安定性能影响很大;油中碱基流失的主要原因是由于在搅拌过程中,烷基水杨酸钙胶团与W/O微乳液发生碰撞,胶团内部的碱基发生了转移;烷基水杨酸钙的水解过程伴随着碳酸钙晶型的变化,由无定形(864 cm-1)变为方解石晶体(875 cm-1)。The hydrolytic stability of calcium alkyl salicylates was investigated, and the effect of stiring time, rotating speed, temperature and quantity of water on calcium alkyl salicylates hydrolytic stability when existing water was analysed. The test data indicates that the effect of stiring time, rotating speed, temperature and quantity of water on calcium alkyl sa- licylates hydrolytic stability is obvious ; the main reason of base decreasing in oil is the transfer of base from a calcium alkyl salicylate particle to an W/O microemulsion droplet during stiring;the crystal type of calcium carbonate is changed from amorphism（864 cm^-1） into calcite crystal（875 cm^-1） during the hydrolization of calcium alkyl salicylate.
