| Abstract: | The ethyl p-hydroxyl benzoate was synthesized with the technique of high-pressure microwave and sodium bisulfate monohydrate as catalyst. Influence factors on the yield were discussed. The yield was 83% under the optimum reaction conditions:molar ratio of alcohol and acid was 4:1, the amount of catalyst was 0.4g, the power of microwave was 522W, the radiating time of microwave was 7min. |
