Title:
INTEGRATED PROCESS FOR MAKING 1-CHLORO-3, 3, 3-TRIFLUOROPROPENE (HCFO-1233ZD) FROM A MIXTURE OF HIGH-BOILING FLUORINATED COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2023/141792
Kind Code:
A1
Abstract:
The present disclosure provides a method for conversion of a mixture of high-boiling fluorinated components comprising 1, 1, 3, 3-tetrachloro-1-fluoropropane (HCFC-241fa), 1, 3, 3-trichloro-1, 1-difluoropropane (HCFC-242fa), 1, 1, 3-trichloro-1, 3-difluoropropane (HCFC-242fb), 3, 3-dichloro-1, 1, 1-trifluoropropane (HCFC-243fa), 1, 3-dichloro-1, 1, 3-trifluoropropane (HCFC-243fb), 3-chloro-1, 1, 1, 3-tetrafluoropropane (HCFC-244fa), their isomers, and combinations thereof, to 1-chloro-3, 3, 3-trifluoropropene (HCFO-1233zd). Heavy impurities, such as oligomers and other high boiling impurities, that are present may be purged during the process to prevent yield loss and reduction of catalyst efficacy.
