Abstract

The present invention relates to azeotrope and azeotrope-like compositions comprised of 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) and 1,1,1,2,3-pentafluoropropane (HFC-245eb), and uses thereof.

First claim

What is claimed is:

1. An azeotrope composition comprising from about 57 to 77.3 wt % of 1-chloro-3,3,3-trifluoropropene and from about 22.7 to 43 wt % 1,1,1,2,3-pentafluoropropane wherein said azeotrope composition has a boiling point of about 18.2° C. to about 18.3° C. at a pressure of about 1.013 bar.

2. The azeotrope composition of claim 1 further comprising a lubricant.

3. The azeotrope composition of claim 2 wherein said lubricant is selected from the group consisting of mineral oil, alkyl benzenes, polyol esters, polyalkylene glycols, polyvinyl ethers, polyalpha olefins, and combinations of two or more thereof.

4. A heat transfer composition comprising a refrigerant consisting of an azeotrope composition of claim 1 .

5. A refrigeration, air conditioning, chilling, or heat pump system comprising a heat transfer composition of claim 4 .

6. A method for cooling an article which comprises condensing a heat transfer composition of claim 4 and thereafter evaporating said refrigerant composition in the vicinity of the article to be cooled.

7. A method for heating an article which comprises condensing a heat transfer composition of claim 4 in the vicinity of the article to be heated and thereafter evaporating said refrigerant composition.

8. The heat transfer composition of claim 4 used as a secondary coolant.

9. A sprayable composition consisting of a material to be sprayed and a propellant comprising an azeotrope composition of claim 1 .

10. A sprayable composition according to claim 9 wherein the sprayable composition is an aerosol.

11. A foamable pre-mix formulation comprising a blowing agent consisting of the composition of claim 1 and a polyol.

12. A foamable pre-mix formulation of claim 11 further comprising at least one surfactant, catalyst, compatibilizer, flame retardant, UV stabilizer, and mixtures thereof.

13. A solvent consisting of the composition of claim 1 .
