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]
trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze(E)) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a , as a blowing agent for foam and aerosol applications, and in air horns and gas dusters . [ 3 ]
cis-1,3,3,3-Tetrafluoropropene (HFO-1234ze(Z), R-1234ze(Z)) is a hydrofluoroolefin which has been considered for use as a refrigerant in high-temperature heat pumps.
Tetrafluoropropene, also called tetrafluoropropylene, has the following isomers: 1,1,2,3-tetrafluoropropene (HFO-1234yc) 1,1,3,3-tetrafluoropropene (HFO-1234zc)
Chemical structure of 1,3,3,3-tetrafluoropropene (HFO-1234ze) Hydrofluoroolefins (HFOs) are unsaturated organic compounds composed of hydrogen, fluorine and carbon. These organofluorine compounds are of interest as refrigerants.

Like the other oxygen fluorides, O 3 F 2 is endothermic and decomposes at about 115 K with the evolution of heat, which is given by the following reaction: 2 O 3 F 2 → O 2 + 2 O 2 F 2. O 3 F 2 is safer to work with than ozone, and can be evaporated, or thermally decomposed, or exposed to electric sparks, without any explosions. But on contact ...
In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature.
