苯丙酮合成工艺改进

Improved Synthesis of Propiophenone

苯丙酮是一重要的有机合成中间体，已有多种方法合成，其中之一是付瑞德尔—克拉夫慈反应。我们对此制备过程进行了改进，用萃取法代替水蒸汽蒸馏，产率达８８．６％。

Propiophenone is a important intermediate in organic synthesis.It has been prepared in some methods.One of them is Friedel-Crafts reaction.In our preparation, the process was improved. It is extraction instead of distillation with steam.Yield is 88.6%.
