对乙基苯甲酸的合成

Synthesis of p-ethylbenzoic acid

以苯和乙酸乙酯为原料 ,无水三氯化铝为催化剂 ,合成了对乙基苯乙酮 ,继而合成了对乙基苯甲酸 ,研究了反应条件对反应的影响。在最佳条件下 ,对乙基苯甲酸的总收率达到 4 6 0 %。

p-Ethylacetophenone was synthesized from benzene and ethyl acetate with catalyst of aluminum trichloride,p-ethylbenzoic acid was then synthesized,and a study of the effect of reaction condition was also conducted,the yield of p-ethylbenzoic acid was 46.0% under the optimum reaction conditions.
