Process for preparing polyfluoroaromatic compounds

摘要

A process for preparing polyfluoroaromatic compounds by heating halogen-containing aromatic compounds with alkali metal fluorides in the presence of a catalyst, N,N',N''-hexa-substituted guanidinium halide, in the medium of products of incomplete fluorination of a halogen-containing compound with simultaneous continuous withdrawal of target products by fractionation or distillation.
