摘要
报道了新型催化剂ＴｉＳｉＷ１２Ｏ４０／ＴｉＯ２ 催化酯化合成葡萄糖五异丁酸酯的糖酸比、催化剂用量、反应时间、反应温度诸因素对产率的影响。实验表明：ＴｉＳｉＷ１２Ｏ４０／ＴｉＯ２ 具有良好的催化活性，糖酸摩尔比为１ ∶５．５，催化剂的用量为反应液的２％ ，酯化反应时间为２ｈ，反应温度１００～１０５℃，反应产率可达８９．６％ 。
The synthesis of glucose pentaisobutyrate using TiSiW 12 O 40 /TiO 2 as catalyst has been studied. The optimum conditions are:molar ratio of glucose to isobutyric acid is 1∶5.5, the quantity of catalyst is equal to 2% feed stock , the reaction temperature is 100～105℃,and the reaction time is 2.0h.TiSiW 12 O 40 /TiO 2 is an excellent catalyst for synthetizing glucose pentaisobutyrate and it's yield can reach over 89.6%.
