Synthesis of sec-butyl acetate catalyzed by strong acid cation exchange resin

The synthesis of sec-butyl acetate by the esterification of 1-butene and acetic acid catalyzed by strong acid cation exchange resin was studied.The effects of the synthesis conditions including molar ratio of 1-butene to acetic acid,reaction pressure,reaction time,reaction temperature and amounts of the catalyst on the acetic acid conversion were studied in detail.The results indicated that under 1-butene/acid ratio 2.0:1,reaction pressure 5.5MPa,reaction time 11h,reaction temperature 120℃,catalyst 1.0g,conversion ratio of acetic acid is 92.4%～95%.Experimental results of Gas chromatograph Mass spectrometer indicated that selectivity to sec-butyl acetate is 92%.The activity and selectivity of catalyst for the esterify reaction is satisfactory,the catalyst can be reused directly for 10 times.
