Summary for Patent: 10,246,670

Title:	Azeotrope-like composition containing fluorinated olefin as component
Abstract:	What is disclosed is a liquid composition containing: 80 mol % to 99.9999 mol % of (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and 0.0001 mol % to 20 mol % of (E)-1,2-dichloro-3,3,3-trifluoropropene (1223E). The liquid composition has small impact on the global environment and exerts azeotrope-like properties. Therefore, the composition of the liquid composition is not substantially changed even when the liquid composition is used in an open system or used for a long period. The composition of the liquid composition is also rarely changed even when the liquid composition is recovered by distillation. Therefore, the liquid mixture according to the present invention can be used suitably as a cleaning agent (a solvent).
