PROBLEM TO BE SOLVED: To provide a novel azeotropic or azeotrope-like mixture which has low environmental load and is safely handled, and in which a change in the liquid composition is less likely to occur.SOLUTION: A liquid composition is provided that is composed of 70 to 99.9999 mol% of (Z)-1-chloro-3,3,3-trifluoro propene (1233Z), and 0.0001 to 30 mol% of (Z)-1,1,1,4,4,4-hexafluoro-2-butene (1336Z).EFFECT: The liquid composition has a small impact on the global environment, and exhibits an azeotrope-like nature. For this reason, the composition variation practically does not occur even when used in an open system or when used for a long period of time. The composition variation is less likely to occur also in the recovery by distillation. For this reason, a liquid mixture of the present invention can be suitably used as a cleaning agent (solvent).SELECTED DRAWING: None |
