2,4——二氯氟苯合成新方法的研究

A New Method of Synthesis of 2,4-Dichlorofluorobenzene

本文提出了一种合成2,4——二氯氟苯的新方法,并对反应条件做了探讨,实验结果表明:在220℃,减压和三氯化催化下,3—氯—氟硝苯通氯生成2,4——二氯氟苯反应的产率可达73.0—75.4％。

In this paper, a new method of systhesis. of 2, 4-Dichlorofluorobenzene was descrbed, and this reaction was studied under different condition. The experimental results showed that FeCl3 was better than AlCl3 and ZnCl3 on their catalytic activities for this reaction.
