METHOD FOR PRODUCING FLUORINE COMPOUND

WIPO Patent Application WO/2011/158790

A1

Provided is a method for producing 1,1,1,4,4,4-hexafluoro-2-butene that is efficient and appropriate for a flow-through reaction. Cis-1,1,1,4,4,4-hexafluoro-2-butene is obtained by isomerization of hexafluoro-1,3-butadiene using a catalyst and then continuous catalytic hydrogen reduction, and in addition cis-1,1,1,4,4,4-hexafluoro-2-butene can be obtained efficiently by carrying out all steps by means of a flow-through catalytic reaction.
