Abstract

Various uses of fluorinated alkenes, particularly HFO-1234 and HFCO-1233zd in a variety of applications, including refrigeration, foams, blowing agents, aerosols, propellants, solvent compositions, fire extinguishing and suppressing agents, extraction agents and catalyst deposition are disclosed.

First claim

What is claimed is:

1. A foamable composition comprising: (i) at least one foam forming component; and (ii) a blowing agent composition comprising:
(a) from 30% to 95% 99% by weight of trans-3,3,3-trifluoro1-chloro-propene (trans-HFCO-1233zd); and
(b) trans-1,3,3,3-tetrafluoropropene (transHFO-1234ze).

2. The foamable composition of claim 1 wherein 3,3,3-trifluoro, 1-chloro-propene (HFCO-1233zd) in said blowing agent consists of trans-3,3,3-trifluoro-1-chloro-propene (trans-HFCO-1233zd).

3. The foamable composition of claim 1 wherein said blowing agent further at least one hydrocarbon selected from the group consisting of iso-pentane, normal-pentane, cyclo-pentane, butane and iso-butane and combinations of these.

4. The foamable composition of claim 1 wherein said blowing agent further comprises trans-1,2-dichloroethylene.

5. The foamable composition of claim 1 wherein said blowing agent further comprises dimethoxymethane.

6. The foamable composition of claim 1 wherein the amount of (a) and (b) together comprise at least about 50% by weight of the blowing agent.

7. The foamable composition of claim 1 wherein said blowing agent further comprises water.

8. The foamable composition of claim 1 wherein said blowing agent further comprises CO 2 .

9. The foamable composition of claim 1 wherein said blowing agent further comprises methylformate.

10. The foamable composition of claim 1 wherein said blowing agent further comprises from 5% to 65% by weight of at least one hydrocarbon selected from the group consisting of iso-pentane, normal-pentane, cyclo-pentane, butane and iso-butane and combinations of these.

11. The foamable composition of claim 10 wherein said blowing agent further comprises water.

12. The foamable composition of claim 11 wherein said water is present in an amount of from 1% to 30% by weight of the blowing agent composition.

13. The foamable composition of claim 1 wherein said at least one foam forming component comprises a thermosetting component-capable of forming a closed cell, thermosetting foam.

14. The foamable composition of claim 1 wherein said at least one foam forming component comprises a thermoplastic component capable of forming a closed cell, thermoplastic foam.

15. The foamable composition of claim 14 wherein said blowing agent comprises from 30% to 70% by weight of said trans-HFO-1234ze.

16. The foamable composition of claim 15 wherein said blowing agent comprises from 60% by weight of said trans-HFO-1233zd.

17. The foamable composition of claim 13 wherein said at least one foam forming component is selected from the group consisting of polyurethane, polyisocyanurate, phenolics and combinations of any two or more of these.

18. The foamable composition of claim 14 wherein said at least one foam forming component is selected from the group consisting polystyrene, polyethylene, and ethylene copolymers, polypropylene, polyethyleneterepthalate and combinations of two or more of these.
