Title: Synthesis of Acetic Ester Using Dodecyl Benzenesulfonic Acid as Catalyst
Abstract: Ethyl acetate(ethyl acetate,n-butyl acetate,benzyl acetate,isoamyl acetate) were synthesized with acetic acid and alcohol(ethanol,butyl alcohol,benzyl alcohol,isoamyl alcohol) as raw materials,and dodecyl benzenesulfonic acid as esterification catalyst by the orthogonal experiments.Effects of feeding ratio,reaction time,reaction temperature and amount of catalyst on the esterification rate were investigated.Under optimum conditions,the esterification rate of the acetates were 83.49%,80.47%,78.39% and 81.57% for ethyl acetate,butyl acetate,benzyl acetate and isoamyl acetate,respectively.This method has the advantages of simple operation,mild reaction conditions and high purity,without use of water-stripping agent,green environmental protection.
