Abstract

The present disclosure provides azeotrope or azeotrope-like compositions including trifluoroiodomethane (CF 3 I) and 1,1,3,3,3-pentafluoropropene (HFO-1225zc), and a method of forming an azeotrope or azeotrope-like composition comprising the step of combining 1,1,3,3,3-pentafluoropropene (HFO-1225zc) and trifluoroiodomethane (CF 3 I) to form an azeotrope or azeotrope-like comprising 1,1,3,3,3-pentafluoropropene (HFO-1225zc) and trifluoroiodomethane (CF 3 I) having a boiling point of about −25.63° C.±0.30° C. at a pressure of about 14.44 psia±0.30 psia.
