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.
Claims23
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%.
