Summary: | PROBLEM TO BE SOLVED: To provide new hydrofluoroolefin (HFO)-based mixtures that are acceptable and environmentally safer substitutes for CFCs, HCFCs, and HFCs, which may be used for HFO production or within one or a combination of applications such as refrigerants, blowing agents and solvents.SOLUTION: A ternary azeotrope or azeotrope-like composition consists essentially of hydrogen fluoride, 2-chloro-3,3,3-trifluoropropene, and a third component selected from the group consisting of 1,1,2,3-tetrachloropropene and 1,1,1,2,2-pentafluoropropane. In the ternary azeotropic or azeotrope-like composition, hydrogen fluoride is present in an amount from about 3.0 to about 28.0 wt.%; 2-chloro-3,3,3-trifluoropropene is present in an amount from about 68.0 to about 93.0 wt.%; and 1,1,2,3-tetrachloropropene is present in an amount from about 2.5 to about 4.3 wt.%.SELECTED DRAWING: None
