摘　　要：Synthetic method of solid superacid TiSiW 12 O 40 /TiO 2 was described.The synthesis of iso amyl propionate catalyzed by TiSiW 12 O 40 /TiO 2 has been studied and the factors influencing on the yield is discussed.It shows that it’s an excellent catalyst,the yield of the iso amyl propionate can be over 77% when the molar ratio of iso amyl alcohol and propionic acid is 1.2,the quality of TiSiW 12 O 40 /TiO 2 is equal to 1.5% feed stock,the reaction time is 80min and the reaction temperature is about 103～107℃.Synthetic method of solid superacid TiSiW 12 O 40 /TiO 2 was described.The synthesis of iso amyl propionate catalyzed by TiSiW 12 O 40 /TiO 2 has been studied and the factors influencing on the yield is discussed.It shows that it's an excellent catalyst,the yield of the iso amyl propionate can be over 77% when the molar ratio of iso amyl alcohol and propionic acid is 1.2,the quality of TiSiW 12 O 40 /TiO 2 is equal to 1.5% feed stock,the reaction time is 80min and the reaction temperature is about 103～107℃.
