PROCEDIMIENTO PARA REACTIVAR CATALIZADOR DE FLUORURO CROMICO GASTADO

摘要

Disclosed herein is a process for reactivating spent chromic fluoride catalyst which can be carbon-supported, comprising reacting the spent catalyst at elevated temperatures with selected chlorine-containing organic compounds and, in certain instances, chlorine. The catalyst is employed in vapor phase halogen exchange between hydrogen fluoride and chlorocarbon compounds to produce fluorocarbon compounds and chlorofluorocarbon compounds.
