The Study on Synthesis Teclmology of Ethyl Acetate Catalyzed by Sodium Bisulfate

With sodium bisulfate as the catalyst,and acetic acid and alcohol as raw materials,ethyl acetate was synthesized.The effects of the reac- tion time,amount of catalyst,molar ratio of acid to alcohol and water carrying agent on esterification rate were discussed and the optimal reaction condi- tions were obtained as follows:based on 0.2 reel alcohol,the molar ratio of acetic acid to alcohol was 1.5:1,the amount of catalyst was 1.5 g,reaction time was 2h,and cyclohexane was 10 mL.Under these conditions,the highest yield of the reaction could reach 85.2%.Sodium bisulfate was a highly active catalyst for this reaction,le~ amount was required.And it was less pollution and contusion,cheap,the esterification rate was high and it could be recycled,so it had a good developing foreground.
