对甲苯磺酸催化合成苯甲酸异戊酯

Catalytia Synthesis of Isoamyl Benzoate with P-Toluene Sulphonic Acid

在对甲苯磺酸存在下 ,由苯甲酸和异戊醇合成苯甲酸戊酯。当苯甲酸、异戊醇和对甲苯磺酸的物质的量比为 1:3:0 .13,回流分水 2h ,酯收率达 99%

Isoamyl benzoate was synthesized from benzoic acid and isoamyl alcohol in the presence of p-toluene sulphonic acid.The yield of the ester could reach 99% under amount of substance ratio of benzoic acid,isoamyl alcohol and p-toluene salphonic acid is 1:3:0.13,refluxing and water segrated for 2h.
