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

1 .- 20 . (canceled)

21 . A method for producing a fluid having improved properties comprising:
(a) providing a first fluid having flammability in air; (b) providing a second fluid comprising transHFO-1234ze; and (c) combining said first fluid and said second fluid to produce a fluid having a flammability in air that is substantially less than the flammability of said first fluid and having no substantial acute toxicity

22 . The method of claim 21 wherein said combining step produces a fluid having no flammability air, a global warming potential (GWP) of not greater than about 1000 and an ozone depletion potential (ODP) not greater than about 0.02.

23 . The method of claim 21 wherein said first fluid comprises flammable hydrocarbon(s).

24 . The method of claim 21 wherein said first fluid comprises flammable hydro fluorocarbon(s).

25 . The method of claim 24 wherein said first fluid comprises HFC-152a.

26 . The method of claim 24 wherein said first fluid comprises HFC-143a.

27 . The method of claim 24 wherein said first fluid comprises HFC-32.

28 . The method of claim 24 wherein said first fluid comprises at least one hydrofluorcarbon selected from the group consisting of HFC-152a, HFC-143a, HFC-32 and combinations of any two or more of these.

29 . The method of claim 21 wherein said combining step produces a fluid having no flammability in air as measured by ASTM E-681.

30 . The method of claim 29 wherein said first fluid comprises flammable hydro fluorocarbon(s).

31 . The method of claim 29 wherein said first fluid comprises HFC-152a and said second fluid consists essentially of transHFO-1234ze.

32 . The method of claim 29 wherein said first fluid comprises HFC-143a and said second fluid consists essentially of transHFO-1234ze.

33 . The method of claim 29 wherein said first fluid comprises HFC-32 and said second fluid consists essentially of transHFO-1234ze.

34 . The method of claim 29 wherein said first fluid comprises at least one hydrofluorcarbon selected from the group consisting of HFC-152a, HFC-143a, HFC-32 and combinations of any two or more of these.

35 . A refrigerant composition comprising a reduced flammability fluid formed according to the method of claim 1 .

36 . A method for cooling comprising providing the refrigerant of claim 35 in a heat transfer system.

37 . A method for cooling the air in an automobile comprising providing the refrigerant of claim 35 in the air conditioning system of the automobile.

38 . A chiller comprising the refrigerant of claim 35 .

39 . A commercial air conditioning system comprising the refrigerant of claim 35 .

40 . A refrigeration system comprising the refrigerant of claim 35 .

41 . An air conditioning system comprising the refrigerant of claim 35 .
