CLAIMS

1. A composition comprising a binary azeotrope or azeotrope-like mixture consisting

essentially of trans-l-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-l,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 azeotrope or azeotrope-like mixture consists essentially of about 75 to about 99.9 weight percent HFO-1234yf and about 0.1 to about 25 weight percent trans-HFO-1233zd.

6. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture consists essentially of about 85 to about 99.9 weight percent HFO-1234yf and about 0.1 to about 15 weight percent trans-HFO-1233zd.

7. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture consists essentially of about 90 to about 99.9 weight percent HFO-1234yf and about 0.1 to about 10 weight percent trans-HFO-1233zd.

8. 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.

9. The composition of claim 1 wherein said azeotrope or azeotrope-like mixture has a boiling point of about -28.5 ± 1 °C at ambient pressure.

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

11. A heat transfer composition comprising the composition of any of claims 1-10.

12. A solvent composition comprising the composition of any of claims 1-10.

13. A sprayable composition comprising the composition of any of claims 1-10.

14. A blowing agent comprising the composition of any of claims 1-10.

15. A foamable composition comprising the blowing agent of claim 14.
