硫酸氢钠可代替硫酸催化酯化作用。在一水硫酸氢钠存在下由正丁醇和苯甲酸合成了苯甲酸正丁酯。当苯甲酸、正丁醇和硫酸氢钠的物质的量比为 1∶2∶0 .0 7,回流分水 2h ,酯收率可达 96 .6 %。本法操作方便 ,反应温和 ,产品纯度和收率高

Sodium bisulfate can be used as catalyst for the esterification instead of sulphuric acid.N-Butyl benzoate is sysnthesized from n-butyl alcohol and benzoic acid in the presence of sodium bisulfate monohydrate(NaHSO 4·H 2O).The yield of the ester reaches 96.6% under amount of substance ratio of benzoic acid,n-butyl alcohol and sodium bisulfate is 1∶2∶0.07,refluxed and water segrated for 2h.This method takes the advantages of simple operation,mild...
