Abstract

Azeotrope-like compositions are disclosed. The azeotrope-like compositions are mixtures of HCFO-E-1-Chloro-3,3,3-trifluoropropene and Cyclopentane. 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 (14)

1 . A composition consisting essentially of:

(a) HCFO-E-1-Chloro-3,3,3-trifluoropropene; and

(b) a pentane; wherein the pentane is present in an effective amount to form an azeotropic or azeotrope-like combination with the HCFO-E-1-Chloro-3,3,3-trifluoropropene, and wherein the pentane is cyclopentane, isopentane, or n-pentane.

2 . The composition of claim 1 , wherein the azeotrope-like composition is:

a) 78-99 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene and 1-22 mole Cyclopentane

b) 1-99 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene and 99-1 mole Isopentane or

c) 57-99 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene and 43-1 mole % n-pentane.

3 . The composition of claim 1 , wherein the azeotropic composition is:

a. About 78-99 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene and about 1-22 mole % cyclopentane

b. about 60.0 mole percent to about 98 mole percent HCFO-E-1-Chloro-3,3,3-trifluoropropene and from about 40.0 mole percent to about 2 mole percent Isopentane;

c. about 1-10 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene d and about 99-90 mole % n-pentane;

d. about 1-99 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene and about 99-1 mole % Isopentane; or

e. about 57-99 mole % HCFO-E-1-Chloro-3,3,3-trifluoropropene and about 43-1 mole % n-pentane.
