Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A 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 composition. 2. The composition of claim 1 , wherein the 2,3,3,3-tetrafluoropropene is present in the composition in an amount of 0.0001 to 0.9 wt. %, based on the total weight of the composition. 3. The composition of claim 1 or 2 , wherein the 1,1,3,3,3-pentafluoropropene is present in the composition in an amount of 0.0001 to 0.9 wt. % based on the total weight of the composition. 4. The composition of claim 3 , wherein the E-1,3,3,3-tetrafluoropropene is present in the-composition in an amount of 50.0 wt. % or more based on the total weight of the-composition. 5. The composition of claim 4 , wherein the total amount of 2,3,3,3-tetrafluoropropene and 1,1,3,3,3-pentafluoropropene in the composition is 0.001 to 0.9 wt. % based on the total weight of the composition. 6. The composition of claim 5 , additionally comprising R-134, in an amount of 1.0 to 40.0 wt. %, based on the total weight of the composition. 7. The composition of claim 5 , additionally comprising R-1336mzzE and R-227ea, in an amount of 15.0 to 20.0 wt. % of R-1336mzzE and of 2.0 to 5.0 wt. % of R-227ea based on the total weight of the composition. 8. The composition of claim 7 , wherein the composition is a near-azeotropic composition. 9. The composition of claim 7 , further comprising a lubricant selected from the group consisting of paraffins, naphthenes aromatics, linear branched alkyl alkylbenzenes, synthetic paraffins, synthetic naphthenes, poly(alphaolefins), polyol esters, polyalkylene glycols, and polyvinyl ethers. 10. A process for transferring heat, comprising: providing an article; and contacting the article with a heat transfer media; wherein the heat transfer media comprises the composition of claim 7 . 11. 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 composition of claim 9 . 12. A chiller apparatus comprising the composition of claim 9 . 13. A method for replacing a high GWP refrigerant in a refrigeration, air conditioning, or heat pump apparatus, wherein the high GWP refrigerant is selected from the group consisting of R134a, R22, R123, R11, R245fa, R114, R236fa, R124, R12, R410A, R4070, R417A, R422A, R507A, R502, and R404A, the method comprising providing the composition of claim 9 to the refrigeration, air conditioning, or heat pump apparatus that uses, used or is designed to use the high GWP refrigerant. 14. A refrigeration apparatus, air-conditioning apparatus, or heat pump apparatus containing the composition of claim 9 , wherein the refrigeration apparatus is a stationary air-conditioning or refrigeration apparatus. 15. The composition of claim 1 further comprising at least one member selected from the group consisting of 236fa, 1225ye (E and Z), and 1234zc. 16. The composition of claim 1 further comprising at least one member selected from the group consisting of 134a, 152b, 1233xf, E-1233zd, and Z-1233zd. 17. The composition of claim 1 further comprising 227ea. 18. The composition of claim 1 further comprising 134. 19. The composition of claim 1 further comprising at least one member selected from the group consisting of 125, 134a and 32. 20. The composition of claim 1 further comprising 1336.
