Abstract:
A process is disclosed for producing compositions including (a) a compound selected from the group consisting of CHF CF , CHF CHF , CH FCF , CH CF , CH CHF , CH FCF CHF and CHF CF CF CHF and (b) at least one saturated halogenated hydrocarbon and/or ether having the formula: 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 (b) does not include the selected component (a) compound, wherein the molar ratio of component (b) to component (a) is between about 1:99 and a molar ratio of HF to component (a) in an azeotrope or azeotrope-like composition of component (a) with HF. This process involves (A) combining (i) the azeotrope or azeotrope-like composition with (ii) at least one fluorination precursor compound wherein the precursor component (ii) is the fluorination precursor to component (b); 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 (a) and (b) in said ratio. In addition, compositions are disclosed comprising component (a) (e. g.
