Azeotrope-like compositions comprising 1-chloro-3,3,3-trifluoropropene
View Patent ↗The present invention relates, in part, to ternary azeotropic compositions and mixtures including chlorotrifluoropropene, methanol, and a third component selected from isohexane, trans-1,2-dichloroethylene, and petroleum ether. The present invention further relates to ternary azeotropic compositions and mixtures including chlorotrifluoropropene, cyclopentane, and a alcohol selected from methanol, ethanol, and isopropanol.

2. A solder flux cleaning composition comprising the composition of claim 1 .
3. A dry cleaning composition comprising the composition of claim 1 .
4. A solvent composition comprising the composition of claim 1 .
5. A vapor degreasing composition comprising the solvent composition of claim 4 .
6. A cold cleaning composition comprising the solvent composition of claim 4 .
7. A wiping composition comprising the solvent composition of claim 4 .
8. A sprayable composition comprising the ternary azeotrope-like composition of claim 1 .
9. An aerosol composition comprising the ternary azeotrope-like composition of claim 1 .
10. The composition of claim 1 comprising from about 20.0 wt. % to about 35 wt. % trans-1,2-dichloroethylene.
11. The composition of claim 1 comprising from about 25.0 wt. % to about 35 wt. % trans-1,2-dichloroethylene.
12. The composition of claim 1 wherein the boiling point of said composition comprising about 20 wt. % to about 40.0 wt. % trans-1,2-dichloroethylene is not greater than the boiling point when said trans-1,2-dichloroethylene is outside of said range of from about 20 wt. % to about 40.0 wt. % trans-1,2-dichloroethylene.
13. A method of cleaning comprising applying a solvent composition comprising a ternary azeotrope-like composition of claim 1 .
14. The method of claim 13 wherein said applying step comprises vapor degreasing.
15. The method of claim 13 wherein said applying step comprises cold cleaning.
