| Abstract: | Researches on the catalysts,carriers and reaction conditions for the synthesis of HFC-134a from trichoroethylene by gasous phase catalytic fluorination,via HCFC-133a intermediate,were reviewed. The mechanisms of halogen exchange reaction were also outline.It is suggested that AlF3 supported metal catalysts with higher fluorinating performance and less Gr3+ or other metal be developed. |
