A composition comprising an azeotrope or azeotrope-like composition consisting essentially of (Z)-1-chloro-2,3,3-trifluoroprop-1-ene, methanol, and trans-dichloroethylene wherein in a ternary composition diagram the (Z)-1-chloro-2,3,3-trifluoroprop-1-ene, methanol, and trans-dichloroethylene are within a quadrilateral region having the following points as vertices:
- point A:
- ((Z)-1-chloro-2,3,3-trifluoroprop-1-ene/methanol/trans-dichloroethylene=about 0.9 wt. %/about 8.2 wt. %/about 90.9 wt. %);
- point B:
- ((Z)-1-chloro-2,3,3-trifluoroprop-1-ene/methanol/trans-dichloroethylene=about 0.9 wt. %/about 13.7 wt. %/about 85.4 wt. %);
- point C:
