磷钼杂多酸的合成、表征及催化活性的研究

Studies on synthesis characterization and catalytic activity of olybdophosphoric-heteropolyacid

介绍了磷钼杂多酸的合成、表征，并以磷钼杂多酸取代硫酸作催化剂制备乙酸乙酯来研究其催化活性，讨论了催化剂用量，反应时间，醇酸摩尔比对收率的影响，并与硫酸做催化剂进行对比，实验收率为９１．４８％，超过硫酸催化剂水平。

It has shown the method of synthesis and the character of olybdophosphoric acid, studied the catalytic activity as catalyst in synthesis ethyl acetate instead of sulphuric acid. Discussed the quantity of catalyst, the time of reaction and effect of the alcohol and ratio of acid on rate of the reaction. Under the optimum conditions, rate of production was 91.48%, which is better than using the sulphuric acid.
