一水硫酸氢钠催化合成苯甲酸酯

Catalytic Synthesis of Benzoic Esters with Sodium Bisulfate Monohydrate

报道了在一水硫酸氢钠催化剂存在下,由苯甲酸和各种醇合成系列苯甲酸酯.获得了苯甲酸、不同醇和硫酸氢钠的摩尔比为1:3(或4):0.2,反应时间2h生成苯甲酸酯的收率.测定了合成苯甲酸酯的沸点、元素分析、红外光谱和核磁共振谱.

Benzoic esters were synthesized from benzoic acid and various alcohol s in the presence of sodium bisulfate monohydrate catalyst.The yields of benzoic esters were given under amount molar ratio of benzoic acid,alcohol and sodium b isulfate 1:3(or 4):0.2 and reaction time of 2 h.The properties of benzoic esters ,such as boiling point,elementary analysis,IR and 1HNMR were measured.
