| Abstract: | The author improved prepare experiment on ethyl acetate from eperiment unit and catalyst, researched preparing eperiment on ethyl acetate that acetic acid and 95% alcocol were chosen as experimental material, and that sodium hydrogen sulphite was chosen as catalyst. From the result of experiment, The optimum reaction conditions were as follows: n(acetic acid ): n(alcocol): n(sodium hydrogen sulphite)= 1:1.65:0.072, and addition reaction time was 30min, productivity was 64.1%. |
