PROCESS FOR PRODUCING 1,1,1,4,4,4-HEXAFLUORO-2-BUTENE AND 1,1,1,4,4,4,-HEXAFLUOROBUTANE

摘要

1,1,1-Trifluoro-2,2-dichloroethane is reacted with metallic copper and an amine to give 1,1,1,4,4,4-hexafluoro-2-butene, which is further reacted with hydrogen to give 1,1,1,4,4,4-hexafluorobutane. This process facilitates the production of not only 1,1,1,4,4,4-hexafluorobutane which is used as a refrigerant, blowing agent or cleaning agent and contributes to the environmental protection, but also 1,1,1,4,4,4-hexafluoro-2-butene which is useful as an intermediate for the above butane and as a monomer of a fluoropolymer in a high yield.
