PROBLEM TO BE SOLVED: To provide a new liquid mixture that has a small load on the environment, is safe in handling, and hardly causes a change in liquid composition.SOLUTION: A liquid composition comprises 80-99.9999 mol% (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and 0.0001-20 mol% (E)-1,2-dichloro-3,3,3-trifluoropropene (1223E).EFFECT: The liquid composition has a small influence on the global environment and exhibits azeotrope-like properties. Consequently, even when the liquid composition is used in an open system or used for a long period of time, the composition fluctuation does not occur practically. The composition fluctuation hardly occurs even when the liquid composition is recovered by distillation. Therefore, the liquid mixture can be suitably used as a cleaning agent (a solvent).SELECTED DRAWING: None 【課題】環境への負荷が少なく、取り扱いも安全であり、液組成の変化が生じにくい、新規の液体混合物の提供。【解決手段】８０〜９９．９９９９モル％の（Ｚ）−１，２−ジクロロ−３，３，３−トリフルオロプロペン（１２２３Ｚ）と、０．０００１〜２０モル％の（Ｅ）−１，２−ジクロロ−３，３，３−トリフルオロプロペン（１２２３Ｅ）とからなる液体組成物。【効果】前記液体組成物は、地球環境への影響が小さく、共沸様の性質を示す。このため、開放系で使用したり、あるいは長時間使用したりしても、組成変動が実用上起こらない。蒸留による回収においても組成変動が生じにくい。このため、前記液体混合物は、洗浄剤（溶剤）として好適に使用することができる。【選択図】なし
