Abstract Solid base catalyst K2O/SBA��15 was prepared by loading potassium nitrate on mesoporous sieve SBA��15 and then was calcined. The samples were characterized by XRD and BET and used as catalyst in the synthesis of methyl oleate. The experimental results showed that when the loaded amount of K2O was 2%, molar ratio of methanol��oleic acid was 2��1��reaction temperature was 180 �棬reaction time was 4 h and the ratio of catalyst to raw material was 5%(weight ratio), the esterification rate was 83��61%. The results also showed that K2O/SBA��15 had a good catalytic effect after resued.
