| Abstract: | Ethyl acetate is synthesized with iron potassium vitriol as catalyst. The influencing factors to the esterification ratio in the reaction are studied. The result indicates that the optimum conditions are as follows： 0.05mol acetic acid, mass of the catalyst is 0.6 g, molar ratio of alcohol to acid is 1.2： 1, dehydrating agent （benzene） is 15mL, and the temperature is 73 -78℃ , reaction time is 120min, the yield is up to 96.78%. |
