Azeotrope or azeotrope-like compositions of trifluoroiodomethane (CF.sub.3I) and 1,1,1,2,2,3,3,-heptafluoropropane (HFC-227ca)

Abstract:

The present disclosure provides azeotrope or azeotrope-like compositions including trifluoroiodomethane (CF.sub.3I) and 1,1,1,2,2,3,3-heptafluoropropane (HFC-227ca), and a method of forming an azeotrope or azeotrope-like composition comprising the step of combining 1,1,1,2,2,3,3-heptafluoropropane (HFC-227ca) and trifluoroiodomethane (CF.sub.3I) to form an azeotrope or azeotrope-like comprising 1,1,1,2,2,3,3-heptafluoropropane (HFC-227ca) and trifluoroiodomethane (CF.sub.3I) having a boiling point of about -24.46.degree. C..+-.0.30.degree. C. at a pressure of about 14.40 psia.+-.0.30 psia.
