NON-CATALYTIC MANUFACTURE OF 1,1,3,3,3-PENTAFLUOROPROPENE FROM 1,1,1,3,3,3-HEXAFLUOROPROPANE

摘要

1,1,3,3,3-Pentafluoropropene (CF₃CH-CF₂, HFC-1225zc) can be produced by pyrolyzing 1,1,1,3,3,3-hexafluoropropane (CF₃CH₂CF₃, HFC-236fa) in the absence of dehydrofluorination catalyst at temperatures of from about 700° C. to about 1000° C. and total pressures of about atmosphere pressure in an empty, tubular reactor, the interior surfaces of which comprise materials of construction resistant to hydrogen fluoride.
