Abstract:
The present invention relates to a method for fluorinating a chlorinated compound including the steps of (a) placing said chlorinated compound in contact with gaseous hydrogen fluoride within a reactor and in the presence of a fluorination catalyst to produce a fluorinated compound, and (b) regenerating the fluorination catalyst used in step a), the step of regenerating the fluorination catalyst including (c) treating said fluorination catalyst with an oxidizing agent to form an oxidized fluorination catalyst, and (d) treating the oxidized fluorination catalyst obtained in step (c) with a gas mixture including a reducing agent.

Claim (Index 34):
A process for the fluorination of a 2,3,3,3-tetrafluoropropene into 1,1,1,2,2-pentafluoropropane comprising:\n (a) contacting, in a reactor, 2,3,3,3-tetrafluoropropene with hydrogen fluoride in gas phase in the presence of a fluorination catalyst to produce 1,1,1,2,2-pentafluoropropane, (b) regenerating the fluorination catalyst used in step a), wherein the step (b) of regenerating the fluorination catalyst comprises: (c) treating said fluorination catalyst with an oxidizing agent-containing gas flow to form an oxidized fluorination catalyst, and (d) treating the oxidized fluorination catalyst obtained in step (c) with a gaseous mixture comprising a reducing agent, wherein the reducing agent is selected from the group consisting of hydrogen, carbon monoxide, nitrogen monoxide, formaldehyde, C 1 -C 6  alkanes and C 1 -C 10  hydrohalocarbons; and (e) reusing the catalyst regenerated in step b) in step a).
