A novel supported liquid phase film catalyst: Supported PdCl_2-(n-C_4H_9)_4N~+Cl~- molten salts was found to be an effective catalyst with good stability for selective hydrodechlorination of CCl_2F_2 (CFC-12) to its alternatives CH2F2 and CHClF2. Addition of CoCl2, GaCl3 and CuCl2 to PdCl_2-(n-C_4H_9)_4N~+Cl~- modifies the catalytic performance of supported molten salts.
