摘要
首次报道了以固载杂多酸盐TiSiW12O40/TiO2为多相催化剂,通过乙酸和乙醇为原料合成乙酸乙脂,并探讨了诸因素对产率的影响。实验表明:TiSiW12O40/TiO2具有良好的催化活性,醇酸物质的量为1.30:1,催化剂用量为反应物料总量的1.0%,反应时间为1.0h,反应温度84—90℃,产率可达69.38%。
The synthesis of ethyl acetate from acetic acid and ethanol was catalyzed by solid super acid TiSiW12O40/TiO2, and the factors influencing on the yield of the reaction were discussed. It showed that the solid super acid TiSiW12O40/TiO2 was an excellent catalyst, the yield of the ethyl acetate could reach over 69.38% under molar ratio of ethyl alcohol and acetic acid 1.3:1, the reaction temperature of 84~90℃, reaction time of 1.0 h and amount of TiSiW12O40/TiO2 solid super acid catalyst of 1.0%.
