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]
1,3,3,3-Tetrafluoropropene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 1,3,3,3-Tetrafluoropropene is a hydrofluoroolefin which has two isomers: cis -1,3,3,3-tetrafluoropropene. trans -1,3,3,3-tetrafluoropropene, used as a refrigerant (R-1234ze (E).)
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.

Tetrafluoropropylene. Tetrafluoropropylene may refer to: 1,3,3,3-Tetrafluoropropylene (HFO-1234ze) 2,3,3,3-Tetrafluoropropylene (HFO-1234yf) This is a Gaseous phase effluent from the decomposition of Teflon when laser cutting it.
Hydrofluoroolefin. 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. Unlike traditional hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), which are saturated ...
Chromatography software is called also Chromatography Data System. [1] It is located in the data station of the modern liquid, gas or supercritical fluid chromatographic systems. This is a dedicated software connected to an hardware interface within the chromatographic system, which serves as a central hub for collecting, analyzing, and ...
Kingston Technology was founded on October 17, 1987, in response to a severe shortage of 1Mbit surface-mount memory chips, [5] Chinese immigrant John Tu designed a new single in-line memory module (SIMM) that used readily available, older-technology through-hole components. In 1990 the company branched out into its first non-memory product line ...
