| Abstract: | Preparation method of new supported nanoheteropolyoxometalats SiW 12O 4- 40-SO 2- 4/TiO 2 was described. The synthesis of ethyl-hexanonate catalyzed by SiW 12O 4- 40-SO 2- 4/TiO 2 has been studied and the factors influencing on the yield of the faction is discussed. It shows that it's an excellent catalyst, the yield of the ethyl-hexanoate can reach 92% when the molar ratio of alcohol and hexanic acid is 1.15, the quality of catalyst is equal to 1% feed stock, the reaction time is 120 min and the reaction temperature is 92~96 °C. |
