摘要
对由氟苯经硝化、氯化制备２，４二氯氟苯的方法进行了改进．实验表明采用反应精馏的氯化方法直接氯化由氟苯经硝化制备的粗品２，４二硝基氟苯能明显提高２，４二氯氟苯的总收率，总收率达７７．２％．
Dichlorofluorobenzene is prepared from fluorobenzene by nitraction and chlorination,the total yield is 77.2%.Experimentat result show that the total yield of 2,4Dichlorofluorobenzene is obviously raised by the method of distilling-chlorinating reaction and directly chlorinating the crude 2,4Dinitrofluorobenzene prepared from fluorobenzene by nitraction.
