The preparation of ethyl p-hydroxybenzoate by the catalytic reaction ofp-hydroxybenzoic acid with ethanol with copper p-toluene sulfonate as catalyst had been studied. 研究了以对羟基苯甲酸、乙醇为原料、对甲苯磺酸铜为催化剂、合成对羟基苯甲酸乙酯(E214),并讨论了催化酯化的影响因素。
Ethyl p-hydroxybenzoate(E214) was synthesized with p-hydroxy benzoic acid and ethanol as raw materials and activated carbon supported tungstosilicic acid as catalyst under microwave irradiation. 借助微波辐射技术,以活性炭负载钨硅酸为催化剂,尼泊金酸和乙醇为原料合成了尼泊金酸乙酯。
