摘要:
The present invention relates to a fluorination process, comprising: an activation stage comprising contacting a fluorination catalyst with an oxidizing agent-containing gas flow for at least one hour; and at least one reaction stage comprising reacting a chlorinated compound with hydrogen fluoride in gas phase in the presence of the fluorination catalyst, so as to produce a fluorinated compound.
