Abstract

An azeotrope-like mixture consisting essentially of a binary azeotrope-like mixture consisting essentially of trans-1-chloro-3,3,3-trifluoropropene (trans-HFO-1233zd) and a second component selected from the group consisting of 2,3,3,3-tetrafluoropropene (HFO-1234yf) and trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze), and combinations of these and various uses thereof.

First claim

The invention claimed is:

1. A binary azeotrope or azeotrope-like mixture consisting essentially of from 2.1 to 6.6 weight percent trans-1-chloro-3,3,3-trifluoropropene (trans-HFO-1233zd) and from 93.4 to 97.9 weight percent 2,3,3,3-tetrafluoropropene (HFO-1234yf).

2. The composition of claim 1 further comprising at least one additional component selected from lubricants, stabilizers, metal passivators, corrosion inhibitors, flammability suppressants, and combinations of these.

3. A heat transfer composition comprising a refrigerant consisting essentially of the composition of claim 1 .

4. The heat transfer composition of claim 3 having a global warming potential (GWP) of less than about 1000.

5. The heat transfer composition of claim 3 having a global warming potential (GWP) of less than about 500.

6. The heat transfer composition of claim 3 having a global warming potential (GWP) of less than about 150.

7. The heat transfer composition of claim 3 having a global warming potential (GWP) of less than about 75.

8. The heat transfer composition of claim 3 classified as being 2L according to ASHRAE standard 34 dated 2010.

9. A heat transfer method comprising transferring heat by causing a phase change in the composition of claim 1 .

10. The composition of claim 1 further comprising at least one additional component selected from co-blowing agent, co-solvent, active ingredient, a material to be sprayed, lubricants, stabilizers, metal passivators, corrosion inhibitors, flammability suppressants, solvents and combinations of these.

11. A solvent composition comprising the composition of claim 1 .

12. A cleaning method comprising applying the solvent composition of claim 11 to a material or object to be cleaned.

13. The cleaning method of claim 12 wherein said applying step comprises spraying.

14. The cleaning method of claim 12 comprising vapor degreasing.

15. A sprayable composition comprising the composition of claim 1 .

16. The sprayable composition of claim 15 in the form of an aerosol.

17. A blowing agent comprising the composition of claim 1 .

18. A closed cell foam comprising a polyurethane-, polyisocyanurate-, or phenolic-based cell wall and a cell gas disposed within at least a portion of the cell wall structure, wherein the cell gas comprises the blowing agent of claim 17 .

19. A polyol premix composition comprising the blowing agent of claim 17 .

20. A foamable composition comprising the blowing agent of claim 17 .

21. The composition of claim 1 wherein said binary azeotrope or azeotrope-like mixture is an azeotropic composition.
