Title:
PROCESS FOR PRODUCING 1,1,1,2,2,4,4,5,5,5-DECAFLUOROPENTANE
Document Type and Number:
WIPO Patent Application WO/1993/016973
Kind Code:
A1
Abstract:
A novel compound, 3,3-dichloro-1,1,1,2,2,4,4,5,5,5-decafluoropentane, as a precursor of a substitute for refrigerants and the like; an economical process for continuously producing the compound in high yield and selectivity by reacting tetrafluoroethylene with difluorodichloromethane in the presence of a Lewis acid catalyst; and a process for producing 1,1,1,2,2,4,4,5,5,5-decafluoropentane in a high yield by reducing the dichlorodecafluoropentane.
