| Abstract: | The p-ethylacetophenone was synthesized with acetylated, ethylbenzene and anhydrous aluminium chloride, then was oxidized to p-ethylbenzoic acid with iodoform reaction. The influence of the reaction conditions, such as the catalyst amount, the reaction temperature and the reaction time, upon the yield of the p-ethylacetophenone were investigated, as well as the influence of the reaction temperature, the reaction time of iodoform reaction, upon the yield of the p-elhylbenzoicacid, The result showed that, the most suitable reaction condition was got when the catalystdose ratio was 2.0 ： 1, 0, the reaction temperature was 70℃, and the reaction time was 5h in the preparation of the p-ethylacetophenone. The most suitable reaction condition was got when the reaction temperature was 70℃, the reaction time was 4h in the preparation of the p-ethylbenzoic acid. |
