Hydrodechlorination of the chlorine-containing saturated impurities CHClF2, CCl2F2, CHClFCF3, CHF2CClF2, CCl2FCF3, CClF2CClF2, and CClF2CF3 having boiling points of -40.8° C., -29.8° C., -12° C., -10.2° C., 3.0° C., 3.6° C., and -38.7° C., respectively, gives CH2F2, CHClF2, CH2FCF3, CHF2CHF2, CHClFCF3, CHF2CClF2, and CHF2CF3 having boiling points of -51.7° C., -40.8° C., -26.5° C., -19.7° C., -12° C., -10.2° C., and -48.5° C., respectively. Further hydrodefluorination of CH2F2 and CH2FCF3 would give CH3F (HFC-41) and CH3CF3 (HFC-143a) boiling at -78.5° C. and -47.6° C., respectively.
