| Abstract: | Researches on the catalysts,carriers and reaction conditions for the synthesis of HFC-134a from trichloroethylene by gasous phase catalytic fluorination,via HCFC-133a intermediate, were reviewed.The mechanisms of halogen exchange reaction were also outlined.It is suggested that A1F3 supported metal catalysts with higher fluorinating performance and less Cr3+ or other metals be developed. |
