硅钨酸催化合成水杨酸甲酯的研究

Studies on Synthesis of Methyl Salicylate by Silicotungstic Acid as Catalyst

报道了以硅钨酸作催化剂合成水杨酸甲酯 ,提出了反应时间、酸醇比、催化剂用量等合适的酯化条件 .结果表明 。

The synthesis of methyl salicylate catalyzed by 12 silicotungstic acid have been reported. The suitable condition of the synthesis had been studied, such as the time of reaction ,the preportion of acid to alcohol,the amount of catalyst etc. The experiment results show that the 12 silicotungstic acid can give a good selectivity and activity.
