Azeotrope or azeotrope-like compositions of 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) and water

Abstract

Heterogenous azeotrope or azeotrope-like compositions comprising 2-chloro-3,3,3-trifluoropropene (HFCO-1233xf) and water which may include from about 0.09 wt. % to about 92.69 wt. % 2-chloro-3,3,3-trifluoropropene (HFCO-1233xf) and from about 7.31 wt. % to about 99.91 wt. % water and having a boiling point between about 12.0° C. and about 13.6° C. at a pressure of between about 12.5 psia and about 16.5 psia. The azeotrope or azeotrope-like compositions may be used to separate impurities, including water, from 2-chloro-3,3,3-trifluoropropene (HFCO-1233xf).
