摘　　要：用自制的固载杂多酸催化剂催化柠檬酸与正丁醇酯化反应合成柠檬酸三丁酯。探讨了催化剂固载量、反应时间、反应温度、酸醇比等因素对反应结果的影响。实验表明，此固载型催化剂不仅反应活性高、酯化率高、反应后处理简单。Supported heteropoly acid catalyst has been prepared and was investigated for the esterification of n butanol with citric acid in the liquid solid system.The product was detected by IR and H 1 NMR spectra.The effects of the quantity of catalyst,reaction time,reaction temperature and the ratio of the reactants were examined.The experimental results showed that the supported heteropoly acid catalyst had high catalytic activity and stability.
