γ AlF_3 supported Cr^(3+) with other minor components (Co 2+ and Mg 2+ ) catalyst exhibits higher activity, selectivity, and stability for synthesis of HFC 134a, HFC 32, HCFC 123, HFC 152a and C 6H 5CF 3 by gas phase fluorination, and has been approved to be an excellent catalyst for F/Cl exchange reactions. The order of the activity of the catalyst for F/Cl exchange reactions is as follows: HClCCH 2?Cl 2CCHCl>CH 2Cl 2?C 6H 5CCl 3>CCl 2CCl 2>CF 3CH 2Cl.
