Abstract

A fluoropropene composition comprising E-1,3,3,3-tetrafluoropropene, 1,1,3,3,3-pentafluoropropene, and 2,3,3,3-tetrafluoropropene, wherein the total amount of 1,1,3,3,3-pentafluoropropene and 2,3,3,3-tetrafluoropropene is 1.0 wt. % or less, based on the total weight of the fluoropropene composition. A method of producing the fluoropropene, composition and methods for using the fluoropropene composition are also disclosed.

Claims (27)

1. A heat transfer media comprising:

(i) a fluoropropene component comprising at least 75 wt. % E-1,3,3,3-tetrafluoropropene (HFO-1234ze (E)) based on the total weight of the media, Z-1,3,3,3-tetrafluoropropene (HFO-1234ze (Z)), and

(ii) at least one or more members selected from one of difluoromethane (R-32), 1,1-difluoroethane (HFC-152a), 1,1,2,2-tetrafluouroethane (HFC-134), 1,1,1,2-tetrafluouroethane (HFC-134a), 1,1,1,2,2-petfluoropropane (HFC-245cb), or 1-chloro-3,3,3-trifluoropropene (HCFO-1224yd),

wherein the amount of Z-1,3,3,3-tetrafluoropropene (HFO-1234ze (Z)), if present, and the total amount of the at least one or more members (ii) is at most 25 wt. % based on the total weight of the media such that the total amount of the media is 100%.

2. The heat transfer media of claim 1 , wherein one of the at least one or more members is selected from one of R-1224yd and R-134a.

3. The heat transfer media of claim 1 , wherein the at least one or more members comprise R-1224yd and R-134.

4. The heat transfer media of claim 1 , wherein the at least one or more members comprise R-1224yd and R-134a.

5. The heat transfer media of claim 1 , wherein the at least one or more members comprise R-32 and R-152a.

6. The heat transfer media of claim 1 wherein each of the at least one or more members is present in an amount of at least 5 wt. % based on the total weight of the media such that the total amount of the media remains at 100%.

7. The heat transfer media of claim 1 wherein the amount of (i) E-1,3,3,3-tetrafluoropropene (HFO-1234ze (E)) based on the total weight of the media is between 75 wt. % and less than 90 wt. %, and the at least one or more members are present in an amount such that the total amount of the media remains at 100%.

8. The heat transfer media of any of claim 7 , wherein the amount of E-1,3,3,3-tetrafluoropropene (HFO-1234ze (E)) based on the total weight of the media is greater than 80 wt. %.

9. The heat transfer media of claim 1 , wherein the at least one or more members include HFC-245cb such that such that the total amount of the media remains at 100%.

10. The heat transfer media of claim 1 wherein R-134 a is present in an amount of greater than 1.0 wt. % based on the total weight of the heat transfer media provided such that the total amount of the media remains at 100%.

11. The heat transfer media of claim 1 , further comprising a lubricant selected from the group consisting of mineral oils, such as paraffins, naphthenes and aromatics, alkylaryls, such as linear and branched alkyl alkylbenzenes, synthetic paraffins, synthetic naphthenes, poly (alphaolefins), polyol esters, polyalkylene glycols, and polyvinyl ethers.

12. A process for transferring heat, comprising providing an article; circulating and contacting the article with the heat transfer media of claim 1 .

13. A refrigeration system, comprising: an evaporator; a condenser; a compressor; an expansion device; and a heat transfer medium, wherein the heat transfer medium comprises the heat transfer media of claim 1 .

14. A method of producing cooling, the method comprising: evaporating the heat transfer media of claim 1 in the vicinity of a body to be cooled and thereafter condensing the fluoropropene composition.

15. A refrigeration apparatus, air-conditioning apparatus, or heat pump apparatus containing the heat transfer media of claim 3 , wherein the refrigeration apparatus is a stationary or mobile refrigeration apparatus, and the air-conditioning apparatus is a mobile air-conditioning apparatus, preferably an automobile air-conditioning apparatus.

16. A process for transferring heat, comprising providing an article; and contacting the article with a heat transfer media composition which comprises the heat transfer media of claim 1 .

17. A refrigeration system, comprising: an evaporator; a condenser; a compressor; an expansion device; and a heat transfer medium, and circulating the heat transfer medium of claim 1 through the system.

18. A method of producing cooling, the method comprising:

evaporating the heat transfer media of claim 1 in the vicinity of a body to be cooled and thereafter condensing the media.

19. A refrigeration apparatus, air-conditioning apparatus, or heat pump apparatus containing the media of claim 1 , wherein the refrigeration apparatus is a stationary or mobile refrigeration apparatus, and the air-conditioning apparatus is a mobile air-conditioning apparatus, preferably an automobile air-conditioning apparatus.

20. A refrigeration apparatus comprising a chiller containing the media of claim 1 .

21. The composition of claim 1 further comprising HFO-1234yf present in an amount between ≥0 and 0.001 wt. % such that the total amount of the media remains at 100%.

22. A process comprising: (1) providing a heat transfer system, said system including a contained supply of the heat transfer media of claims 1 , and (2) circulating the media through the system.

23. The process of claim 22 wherein the heat system includes a compressor and the compressor provides a motive force to circulate the media.
