Abstract
The sodium bisulfate and concentrated sulfuric acid can be used as a catalyst for esterification. Using acetic acid and n-butyl as raw material, sodium bisulfate and sulfuric acid catalyst for the synthesis of n-butyl acetate compound were studied. The optimum reaction conditions are as follows: acid molar ratio n(acetic acid)∶n(n-butyl)was 1:1.65, the amount of catalyst 1.65 g, Complex catalyst in concentrated sulfuric acid and sodium hydrogen sulfate ratio of 1:0.17, and the reaction time was one hundred and twenty minutes(125min). Esterification rate can be up to 97.6%.
