固体酸催化合成苯甲酸乙酯

Catalytic Synthesis of Ethyl Benzoate with Solid Acid

固体酸能代替硫酸作为酯化催化剂。文章介绍了甲基磺酸、对甲苯磺酸、氨基磺酸、六水三氯化铁、五水四氯化锡、氯化镧、一水硫酸氢钠、壳聚糖硫酸盐、固体超强酸和二氧化硅负载磷钨酸等固体酸催化制备苯甲酸乙酯的方法。

Solid acid can be used as catalyst for the esterification instead of sulphuric acid. The preparation method of ethyl benzoate catalyzed by methyl sulfonic acid, p-toluene sulfonic acid, amino sulfonic acid, ferric chloride hexahydrated, stannic chloride pentahydrate, lanthanun chloride, sodium bi sulfate monohydrate, chitosan sulfate, solid super acid and silicon dioxide support phosphotungstic acid etal solid acid were reviewed.
