摘要
以１２－磷钨酸做催化剂合成了水杨酸甲酯，提出了合适的催化条件。结果表明磷钨酸具有较高的催化活性和较高的催化选择性、酯化率达７０％以上。
The synthesis of methyl salicylate catalyzed by 12-tungstophosphoric-acid has been reported. The suita-ble condition of the synthesis has been studied such as the proportion of acid to alcohol, the amount of cata-lyst ete. The experiment result shows that the 12-tungstophophoric acid can give a good selectivity, activity andhigher productivity.
