| Abstract: |
| With potassium bisulfate as the catalyst,ethyl chloroacetate was synthesized by chloroacetic acid and ethyl alcohol under the following optimized conditions:0.1 mol of chloroacetic as the criterion,1:3.5 of molar ratio of chloroacetic acid to ethyl alcohol,15 ml of cyclohexane,1.0 g of catalyst and 150 min of reaction time.The yield of ethyl chloroacetate reached 74.6%. |
| Key words: ethyl chloroacetate potassium bisulfate catalytic |
