微波促进H3PO4催化对羟基苯甲酸丁酯的合成
Phosphoric Acid Catalytic Synthesis of Butyl p-hydroxybenzoate Under Microwave Irradiation
【摘要】 以H3PO4为催化剂,在微波促进无溶剂条件下合成了对羟基苯甲酸丁酯.研究了酸醇比、催化剂用量、微波辅射功率和辐射时间对对羟基苯甲酸丁酯产率的影响.该方法操作简便、时间短、产率高.
【Abstract】 The phosphoric acid was used as a catalyst to synthesize butyl p-hydroxybenzoate under microwave irradiation without any solvent and inorganic carrier. The influences of the amount of the catalyst, the molar ratio of alcohol to the acid and the irradiation time on the yield of ester were investigated.
