| Abstract: | The synthesis of butyl acetate by the esterifi cation of butyleneand acetic acid catalyzed by 12-phosphorotungstic acid supported on surface-modified activated carbon was studied. The synthesis conditions incluing reaction time, reaction pr essure, reaction temperature ratio of acid/butylene and ageing time of catalyst ec t were studied in detail. The proper feedstock proportion and the experimental p arameters of the esterify reaction were evaluated. Under acid/butylene ratio 1.0 , acetic acid 16 g, butylene 100 mL, catalyst 2.5 g, pressure 1.5 MPa, temperatu re 120 ℃ and reaction time 7 h, conversion ratio of acetic acid is 85.8%. Exper imental results of gas chromatography indicated that selectivity to butyl acetate is close to 1 00%, the activity and selectivity of catalyst for the esterify reaction is satis factory. |
