| Abstract: | The esterification of acetic acid with sec-butanol catalyzed by p-toluenesulfonic acid is reported,and the amount of catalysts,the mole ratio of sec-butanol to acetic acid and reaction time on the yield of sec-butyl acetate is studied.The results show that the best reaction conditions are as the followings：when the amount of acetic acid is 0.1mol,the mass of catalysts is 0.4g,the molar ratio of sec-butanol to acetic acid is 1.2,cyclohexane as the water-carrying agent is 10 ml.The yield of sec-butyl acetate reaches 94.4% in 1.5 h. |
