摘要
硫酸氢钠可代替硫酸催化酯化反应 ,探讨了硫酸氢钠催化合成富马酸二甲酯的反应条件。当酸、醇和催化剂的摩尔比为 1∶12∶0 11,回流 4h ,酯收率达 70 8%。
Sodium bisulfate (NaHSO 4·H 2O) can be used as catalyst for the esterification instead of sulphurie acid.We deal with the conditions in synthesis of dimethyl fumarate catalyzed with sodium bisulfate hydrate (NaHSO 4·H 2O).The yield of the ester could reach 70.8% under molar ratio of fumaric acid,methyl alcohol and sodium bisulfate were 1∶12∶0.11,refluxing for 4 h.
