Abstract

Azeotrope-like compositions are disclosed. The azeotrope-like compositions are mixtures of E-1-chloro-2,3,3,3-tetrafluoropropene with E-1,1,1,4,4,4-hexafluoro-2-butene or E-1,1,1,4,4,5,5,5-octafluoro-2-pentene. Also disclosed is a process of preparing a thermoplastic or thermoset foam by using such azeotrope-like compositions as blowing agents. Also disclosed is a process of producing refrigeration by using such azeotrope-like compositions. Also disclosed is a process of using such azeotrope-like compositions as solvents. Also disclosed is a process of producing an aerosol product by using such azeotrope-like compositions. Also disclosed is a process of using such azeotrope-like compositions as heat transfer media. Also disclosed is a process of extinguishing or suppressing a fire by using such azeotrope-like compositions. Also disclosed is a process of using such azeotrope-like compositions as dielectrics.

Claims (10)

1. A composition consisting essentially of:

(a) E-1-chloro-2,3,3,3-tetrafluoropropene; and

(b) a component selected from the group consisting of E-1,1,1,4,4,4-hexafluoro-2-butene and E-1,1,1,4,4,5,5,5-octafluoro-2-pentene; wherein said component is present in an effective amount to form an azeotrope-like combination with the E-1-chloro-2,3,3,3-tetrafluoropropene.

2. A process for preparing a thermoplastic or thermoset foam comprising using the azeotrope-like composition of claim 1 as a blowing agent.

3. A process for producing refrigeration comprising condensing the azeotrope-like composition of claim 1 and thereafter evaporating said azeotrope-like composition in the vicinity of the body to be cooled.

4. A process comprising using the azeotrope-like composition of claim 1 as a solvent.

5. A process for producing an aerosol product comprising using the azeotrope-like composition of claim 1 as a propellant.

6. A process comprising using the azeotrope-like composition of claim 1 as a heat transfer media.

7. A process for extinguishing or suppressing a fire comprising using the azeotrope-like composition of claim 1 as a fire extinguishing or suppression agent.

8. A process comprising using the azeotrope-like composition of claim 1 as dielectrics.
