微波作用下对甲苯磺酸催化合成对羟基苯甲酸甲酯

The Microwave Synthesis of Methyl p-Hydroxybenzoate with p-Methyl-benzene Sulfonic Acid Catalyzed

利用微波技术,采用正交实验方法,用对甲苯磺酸为催化剂微波辐射合成了对羟基苯甲酸甲酯。与常规加热法比较,微波合成对羟基苯甲酸酯类化合物有反应时间短,产物易纯化的特点。

The microwave synthesis of methyl p - hydroxybenzoate with p- methyl- benzene- sulfonie acid catalyzed. Compared with conventional heating method, microwave synthesis of p- hydroxybenzoie ester cost short time and the product was purified easy.
