混合酸催化合成水杨酸异丙酯研究

Research on Mixed Acid Catalyst for the Synthesis of Isopropyl Salicylate

首次以磷钨酸、对甲苯磺酸、硼酸的混合酸为催化剂 ,以水杨酸和异丙醇为原料 ,合成了水杨酸异丙酯 ,考察了影响反应的因素 。

The article introduces synthesis of isopropyl salicylate with mixed acid (the mixture of phosphotungstic acid,p toluenesulfonic acid,boric acid) as catalyst.The optimum preparation conditions have been obtained.It is observed that this catalyst show high catalytic active for synthesizing isopropyl salicylate.
