2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH 2 =CFCF 3. Its primary application is as a refrigerant with low global warming potential (GWP). [ 1][ 2] As a refrigerant, it is designated R-1234yf[ 1] and marketed under the names Opteon YF by Chemours and as Solstice YF by Honeywell. [ 3]
DuPont. DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company first formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours. The company played a major role in the development of the U.S. state of Delaware and first arose as a major supplier of gunpowder.
Later in his career, Plunkett was the chief chemist involved in the production of tetraethyllead, an antiknock agent that made gasoline "leaded," later discontinued over concerns about the toxic effects of lead. After that, he directed the production of Freon, DuPont's brand name for chlorofluorocarbon refrigerant, before retiring in 1975. [7]

R-410A. R-410A is a refrigerant used in air conditioning and heat pump applications. It is a zeotropic but near- azeotropic mixture of difluoromethane (CH 2 F 2, called R-32) and pentafluoroethane (CHF 2 CF 3, called R-125). R-410A is sold under the trademarked names AZ-20, EcoFluor R410, Forane 410A, Genetron R410A, Puron, and Suva 410A.

A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated because of their toxicity and flammability and the contribution of CFC and HCFC refrigerants to ozone ...
