摘要
本文报道了杂多酸—１２－钨磷酸催化合成柠檬酸三丁酯的实验方法和实验结果。对实验条件如酯化时间、原料比、催化剂用量等进行了探索；提出了合适的酯化条件。并利用气相色谱对反应速率进行了初步考察。结果表明：磷钨酸对催化合成柠檬酸三丁酯具有良好的催化效果，酯化率接近１００％，收率达９７％。
the synthesis of n butyl citricate catalyzed by 12 tungsto phosphoric acid have been reported.The suitable conditions of the synthesis have been studied,such as the time of reaction,the proportion of acid to alcohol the amount of catalyst etc.The experiment results show that the heteropolyacid can give a good selectivity,activity and high productivity.
