Title:
PROCESS FOR THE MANUFACTURE OF 1,3,3,3 TETRAFLUOROPROPENE
Document Type and Number:
WIPO Patent Application WO2005012212
Kind Code:
A3
Abstract:
The invention provides an economic process for the manufacture of 1,3,3,3tetrafluoropropene (HFC-1234ze) by a two stage process. A hydr6fluorination of 1-chloro-3,3,3-trifluoropropene (HCFC-1233zd) into 1-chloro.-1,3,3,3 tetrafluoropropane (HCFC-244fa) and 1,1,1,3,3-pent afluoropropane (HFC 245fa) is conducted, followed by the dehydrochlorination of (HCFC-244)fa and dehydrofluorination of (HFC-245)fa into (HFC-1234)ze.
