2,4-二氯氟苯的合成新工艺

Studies on the Compose of a New Method of 2,4-Dichlorfluorober Zene

主要对用１，４－二氯苯合成２，４－二氯氟苯新的合成方法进行了研究，得出了硝化、氟代和氯代的最优反应条件。实验表明：在这种条件下异构体少、提纯容易而且原料便宜。

A a new synthetic method of 2,4-dichlorofluorobenzene from 1,4-dichlorobenzene was investigated.The optium veaction conditions of nitrification,fluorination and cholorination is obtained.The results show that:in this case,the less alloisomers、the easier purified、the cheap initial substances were obtainable.
