对乙基苯甲酸的合成

Study on Synthesis of p-Ethylbenzoic Acid

以乙苯和三氯乙醛为原料,制成1-对乙苯基-2,2,2-三氯乙醇,再用双氧水氧化合成对乙基苯甲酸。考察了反应条件对反应收率的影响,结果表明反应收率可达91.8%,产品纯度在98%以上。

1-p-ethylbenzene-2,2,2-tricholro ethanol has been achieved from ethylbenzene and chloral, the product is then oxided by H2O2, which constitutes a convenient synthesis of p-ethylbenzoic acid. The factors affected the reaction were studied and the result indicates that the yield and purity of p-ethylbenzoic acid can reach above 91.8% and 98% respectively.
