| Abstract: | 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. |
