Abstract

Azeotropic or azeotrope-like compositions are disclosed. The azeotropic or azeotrope-like compositions are mixtures of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene with a second compound selected from the group consisting of methyl formate and HFO-E-1,1,1,4,4,4-hexafluoro-2-butene. Also disclosed are processes of preparing a thermoplastic or thermoset foam by using such azeotropic or azeotrope-like compositions as blowing agents; of producing refrigeration by using such azeotropic or azeotrope-like compositions; of producing cooling; of producing heating; of using such azeotropic or azeotrope-like compositions as solvents; of producing an aerosol product by using such azeotropic or azeotrope-like compositions; of using such azeotropic or azeotrope-like compositions as heat transfer media; of extinguishing or suppressing a fire by using such azeotropic or azeotrope-like compositions; and of using such azeotropic or azeotrope-like compositions as dielectrics.

First claim

What is claimed is:

1. A composition consisting essentially of:
(a) HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and
(b) methyl formate; wherein the methyl formate is present in an effective amount to form an azeotropic composition with the HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene.

2. The composition of claim 1 , consisting essentially of:
(a) from about 11.2 mole percent to about 46.5 mole percent HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and
(b) from about 53.5 mole percent to about 88.8 mole percent methyl formate.

3. The composition of claim 2 , consisting essentially of:
(a) about 42.1 mole percent HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and
(b) about 57.9 mole percent methyl formate.

4. A composition consisting essentially of:
(a) HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and
(b) methyl formate; wherein the methyl formate is present in an effective amount to form an azeotrope-like composition with the HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene.

5. The composition of claim 4 , consisting essentially of:
(a) from about 1 to 99 mole percent HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and
(b) from about 1 to 99 mole percent methyl formate.

6. A process for preparing a thermoplastic or thermoset foam comprising using the azeotropic composition of claim 1 as a blowing agent.

7. A process for producing refrigeration comprising condensing the azeotropic composition of claim 1 and thereafter evaporating said azeotropic composition in the vicinity of a body to be cooled.

8. A process comprising using the azeotropic composition of claim 1 as a solvent.

9. A process for producing an aerosol product comprising using the azeotropic composition of claim 1 as a propellant.

10. A process comprising using the azeotropic composition of claim 1 as a heat transfer media.

11. A process for extinguishing or suppressing a fire comprising using the azeotropic composition of claim 1 as a fire extinguishing or suppression agent.

12. A process comprising using the azeotropic composition of claim 1 as a dielectric.

13. A process for producing cooling, comprising condensing the azeotropic composition of claim 1 and thereafter evaporating said azeotropic composition in the vicinity of the body to be cooled.

14. A process for producing heating, comprising condensing the azeotropic composition of claim 1 in the vicinity of a body to be heated and thereafter evaporating said azeotropic composition.

15. A process for preparing a thermoplastic or thermoset foam comprising using the azeotrope-like composition of claim 4 as a blowing agent.

16. A process for producing refrigeration comprising condensing the azeotrope-like composition of claim 4 and thereafter evaporating said azeotrope-like composition in the vicinity of a body to be cooled.

17. A process comprising using the azeotrope-like composition of claim 4 as a solvent.

18. A process for producing an aerosol product comprising using the azeotrope-like composition of claim 4 as a propellant.

19. A process comprising using the azeotrope-like composition of claim 4 as a heat transfer media.

20. A process for extinguishing or suppressing a fire comprising using the azeotrope-like composition of claim 4 as a fire extinguishing or suppression agent.

21. A process comprising using the azeotrope-like composition of claim 4 as a dielectric.

22. A process for producing cooling, comprising condensing the azeotrope-like composition of claim 4 and thereafter evaporating said azeotrope-like composition in the vicinity of the body to be cooled.

23. A process for producing heating, comprising condensing the azeotrope-like composition of claim 4 in the vicinity of a body to be heated and thereafter evaporating said azeotrope-like composition.
