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.

Claims (29)

1. A composition comprising a binary azeotrope or azeotrope-like mixture consisting essentially of trans-1-chloro-3,3,3-trifluoropropene (trans-HFO-1233zd) and trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze).

2. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture consists essentially of about 80 to about 99.9 weight percent trans-HFO-1234ze and about 0.1 to about 20 weight percent trans-HFO-1233zd.

3. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture consists essentially of about 83 to about 99.9 weight percent trans-HFO-1234ze and about 0.1 to about 17 weight percent trans-HFO-1233zd.

4. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture consists essentially of about 97 to about 99.7 weight percent trans-HFO-1234ze and about 0.3 to about 3 weight percent trans-HFO-1233zd.

5. The composition of claim 1 wherein said trans-HFO-1233zd is present in an amount that is not greater than about 25 weight percent of said binary azeotrope or azeotrope-like mixture.

6. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture has a boiling point of about −18.5±1° C. at ambient pressure.

7. 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.

8. A heat transfer composition comprising the composition of claim 1 .

9. The heat transfer composition of claim 8 having a global warming potential (GWP) of less than about 1000.

10. The heat transfer composition of claim 8 having a global warming potential (GWP) of less than about 500.

11. The heat transfer composition of claim 8 having a global warming potential (GWP) of less than about 150.

12. The heat transfer composition of claim 8 having a global warming potential (GWP) of less than about 75.

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

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

15. 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.

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

17. A cleaning method comprising applying the solvent composition of claim 16 to a material or object to be cleaned.

18. The cleaning method of claim 17 wherein said applying step comprises spraying.

19. The cleaning method of claim 17 comprising vapor degreasing.

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

21. The sprayable composition of claim 20 in the form of an aerosol.

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

23. 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 22 .

24. A polyol premix composition comprising the blowing agent of claim 22 .

25. A foamable composition comprising the blowing agent of claim 22 .

26. A thermoplastic foam having a cell wall comprising a thermoplastic polymer and a cell gas comprising the composition of claim 1 .

27. The thermoplastic foam of claim 26 wherein the thermoplastic polymer is selected from the group consisting of polystyrene, polyethylene, polypropylene, polyvinyl chloride, polytheyeneterephthalate, and combinations thereof.

28. The thermoplastic foam of claim 26 wherein the thermoplastic polymer comprises polystyrene.

29. The thermoplastic foam of claim 26 wherein the thermoplastic foam is an extruded foam and the thermoplastic polymer comprises polystyrene.
