Abstract

Disclosed is a mixture comprising the compound trans-1,1,1,4,4,4-hexafluoro-2-butene and at least one additional compound selected from the group consisting of HFOs, HFCs, HFEs, CFCs, CO2, olefins, organic acids, alcohols, hydrocarbons, ethers, aldehydes, ketones, and others such as methyl formate, formic acid, trans-1,2 dichloroethylene, carbon dioxide, cis-HFO-1234ze+HFO-1225yez, mixtures of these plus water; mixtures of these plus CO2; mixtures of these trans 1,2-dichloroethylene (DCE); mixtures of these plus methyl formate; mixtures with cis-HFO-1234ze+CO2, mixtures with cis-HFO-1234ze+HFO-1225yez+CO2, and mixtures with cis-HFO-1234ze+HFC-245fa. Also disclosed are methods of using and products of using the above compositions as blowing agents, solvents, heat transfer compositions, aerosol propellant compositions, fire extinguishing and suppressant compositions.

First claim

What is claimed is:

1. A mixture comprising the compound trans-1,1,1,4,4,4-hexafluoro-2-butene, HFC-134, and a lubricant.

2. The mixture of claim 1 , wherein the amount of trans-1,1,1,4,4,4-hexafluoro-2-butene is from about 1 to about 99 weight percent.

3. The mixture of claim 1 , wherein the amount of trans-1,1,1,4,4,4-hexafluoro-2-butene is from about 1 to about 50 weight percent.

4. The mixture of claim 1 , wherein the amount of trans-1,1,1,4,4,4-hexafluoro-2-butene is from about 10 to about 80 weight percent.

5. The mixture of claim 1 , wherein the amount of trans-1,1,1,4,4,4-hexafluoro-2-butene is from about 5 to about 60 weight percent.

6. The mixture of claim 1 , wherein the lubricant comprises at least one of polyol esters, and polyalkylene glycols, polyvinyl ethers, fluorinated and perfluorinated oils, polycarbonates, silicone oil, mineral oil, alkyl benzenes, poly(alpha)-olefins, or combinations thereof.

7. The mixture of claim 1 , further comprising at least one additive selected from the group consisting of compatibilizers, surfactants, solubilizing agents, flammability suppressants, and perfluoropolyethers.

8. A method for producing cooling which comprises evaporating a refrigerant comprising a mixture of claim 1 , in the vicinity of a liquid or body to be cooled.

9. A method for producing heating which comprises condensing a refrigerant comprising a mixture of claim 1 , in the vicinity of a liquid or body to be heated.

10. An air conditioning, heat pump or refrigeration system containing a refrigerant comprising a mixture of claim 1 .

11. The system of claim 10 , comprising a commercial refrigeration system.

12. The system of claim 10 , comprising a medium or low temperature refrigeration system.

13. The system of claim 10 , comprising a transport refrigeration system.

14. The system of claim 10 , comprising a residential refrigerator or freezer.

15. The system of claim 10 , comprising a heat pump.

16. The system of claim 10 , comprising a high temperature heat pump.

17. The system of claim 10 , comprising a chiller.
