The process involves hydrodehalogenating CF3CCl2CF3 with hydrogen at an elevated temperature in the vapor phase over a catalyst comprising an elemental metal, metal oxide, metal halide and/or metal oxyhalide (the metal being copper, nickel, chromium and the halogen of said halides and said oxyhalides being fluorine and/or chlorine. Processes for producing the hydrofluorocarbons CF3CH2CHF2, CF3CHFCF3 and CF3CH2CF3 are also disclosed which involve (a) hydrodehalogenating CF3CCl2CF3 with the hydrogen as indicated above to produce a product comprising CF3CCl═CF2, CF3CH═CF2, HCl and HF; and (b) either reacting the CF3CCl═CF2 and/or CF3CH═CF2 produced in (a) in the vapor phase with hydrogen to produce CF3CH2CHF2, reacting CF3CCl═CF2 produced in (a) with HF to produce CF3CHFCF3, or reacting the CF3CH═CF2produced in (a) with HF to produce CF3CH2CF3. Azeotrope compositions of CF3CHFCH3 with HF, and a process for recovering HF from a product mixture comprising HF and CF3CHFCF3 are also disclosed. Also disclosed are compositions and a process for producing compositions comprising (c1) CF3CHFCF3, CF3CH2CF3 or CHF2CH2CF3 and (c2) at least one saturated halogenated hydrocarbon and/or ether having the formula: CnH2n+2−a−bClaFbOc wherein n is an integer from 1 to 4, a is an integer from 0 to 2n+1, b is an integer from 1 to 2n+2−a, and c is 0 or 1, provided that when c is 1 then n is an integer from 2 to 4, and provided that component (c2) does not include the selected component (c1) compound, wherein the molar ratio of component (c2) to component (c1) is between about 1:99 and a molar ratio of HF to component (c1) in an azeotrope or azeotrope-like composition of component (c1) with HF. The process involves (A) combining (i) the azeotropic composition with (ii) the fluorination precursor to component (c2); and (B) reacting a sufficient amount of the HF from the azeotrope or azeotrope-like composition(i) with precursor component (ii) to provide a composition containing components (c1) and (c2) in the desired ratio. The compositions include at least two (c1) compounds, at least one of which is an ether.
