摘要
介绍了以2，4-二硝基氯苯为原料合成DCFB的工艺改进，采用了混合溶剂氟化，反应精馏氯化，使得该工艺安全可靠，质量、总收率得到明显提高。
An improved synthesis of 2, 4-dichlorofluorobenzene was introduced from 2, 4di-nitrochlorobenzene via mixed solvent fluorate,reactive distilled chlorate. The process was safe and reliable. Total yield and quality were improved considerably.
