A process is disclosed for making CH2CICF2CCIF2. The process involves reacting CH2CIF with CCIF=CF2 in an addition reaction zone in the presence of an aluminum halide composition having a bulk formula of AICIxBryF3-x-y wherein the average value of x is 0 to 3, the average value of y is 0 to 3-x, provided that the average values of x and y are not both 0. Also disclosed is a process for making CH2FCF2CF3 that involves reacting the CH2CICF2CCIF2 with HF in a fluorination reaction zone in the presence of a fluorination catalyst. Also disclosed is a process for making CHF=CFCF3 that involves dehydrofluorinating the CH2FCF2CF3.
