Abstract

Disclosed are the use of fluorine substituted olefins, including tetra- and penta-fluoropropenes, in a variety of applications, including in methods of depositing catalyst on a solid support, methods of sterilizing articles, cleaning methods and compositions, methods of applying medicaments, fire extinguishing/suppression compositions and methods, flavor formulations, fragrance formulations and inflating agents.

First claim

What is claimed is:

1. A method of transferring heat to, or from, a fluid or body, said method comprising contacting said fluid or body with a heat transfer composition comprising a refrigerant comprising HFO-1234ze, wherein the HFO-1234ze is at least 90% by weight transHFO-1234ze.

2. The method of claim 1 wherein the heat transfer composition comprises HFO-1234ze in an amount of 5% to 99% by weight.

3. The method of claim 1 wherein the heat transfer composition comprises HFO-1234ze in an amount of at least about 50% by weight.

4. The method of claim 3 wherein the heat transfer composition comprises HFO-1234ze in an amount of at least about 70% by weight.

5. The method of claim 1 wherein the HFO-1234ze is at least 95% by weight transHFO-1234ze.

6. The method of claim 5 wherein the HFO-1234ze is at least 97% by weight transHFO -1234ze.

7. The method of claim 1 wherein the HFO-1234ze is no more than 10% by weight cisHFO-1234ze.

8. The method of claim 5 wherein the HFO-1234ze is no more than 5% by weight cisHFO-1234ze.

9. The method of claim 6 wherein the HFO-1234ze is no more than 3% by weight cisHFO-1234ze.

10. The method of claim 1 comprising the steps of (1) evaporating the heat transfer composition to produce refrigerant vapor, (2) compressing the refrigerant vapor to produce compressed refrigerant vapor, (3) condensing the compressed refrigerant vapor to form refrigerant liquid, and (4) reducing the pressure of the refrigerant liquid.

11. The method of claim 1 wherein the contacting occurs in an automobile air conditioning system.

12. The method of claim 1 wherein the contacting occurs in a commercial refrigeration system.

13. The method of claim 1 wherein the contacting occurs in a chiller.

14. The method of claim 1 wherein the contacting occurs in a residential refrigerator.

15. The method of claim 1 wherein the contacting occurs in a residential freezer.

16. The method of claim 1 wherein the contacting occurs in an air conditioning system.

17. The method of claim 1 wherein the contacting occurs in a heat pump.

18. A heat transfer composition comprising a refrigerant and another component wherein the refrigerant comprises HFO-1234ze and wherein the HFO-1234ze is at least 90% by weight transHFO-1234ze, and wherein the other component is selected from the group consisting of a lubricant, a compatibilizer, a surfactant, a solubilizing agent, a flammability suppressant and mixtures thereof.

19. The heat transfer composition of claim 18 comprising 5% to 99% by weight HFO-1234ze.

20. The heat transfer composition of claim 18 comprising at least 50% by weight HFO-1234ze.

21. The heat transfer composition of claim 20 comprising at least 70% by weight HFO-1234ze.

22. The heat transfer composition of claim 18 wherein the lubricant is selected from the group consisting of polyol esters, poly alkylene glycols, silicone oil, mineral oil, alkyl benzenes and poly(alpha-olefins).

23. The heat transfer composition of claim 22 wherein the lubricant is a polyol ester.

24. The heat transfer composition of claim 23 wherein the lubricant is a poly alkylene glycol.

25. The heat transfer composition of claim 22 wherein the lubricant comprises from 30 to about 50 percent by weight of the composition.

26. The heat transfer composition of claim 18 wherein the HFO-1234ze is at least 95% by weight transHFO-1234ze.

27. The heat transfer composition of claim 26 wherein the HFO-1234ze is at least 97% by weight transHFO-1234ze.

28. The heat transfer composition of claim 18 wherein the HFO-1234ze is no more than 10% by weight cisHFO-1234ze.

29. The heat transfer composition of claim 26 wherein the HFO-1234ze is no more than 5% by weight cisHFO-1234ze.

30. The heat transfer composition of claim 27 wherein the HFO-1234ze is no more than 3% by weight cisHFO-1234ze.
