PROBLEM TO BE SOLVED: To provide azeotrope-like compositions having very low global warming potential, low ozone depletion potential, exhibiting relatively constant boiling point characteristics, and thus, to provide azeotrope-like compositions which is not substantially fractionated on boiling and evaporation.SOLUTION: There is provided a composition comprising a ternary azeotrope-like mixture consisting essentially of 1-chloro-3,3,3-trifluoropropene, trans-1,2-dichloroethylene and a third component selected from the group consisting of methanol, ethanol, n-pentane and isohexane.
