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]
A flip book, flipbook, [1] flicker book, or kineograph is a booklet with a series of images that very gradually change from one page to the next, so that when the pages are viewed in quick succession, the images appear to animate by simulating motion or some other change. Often, flip books are illustrated books for children, but may also be ...
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 ]
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.
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.
2. Read Part One and Part Two as preparation for your workshop, perhaps making notes as you read. When you've finished, set aside three hours and write your answers to the questions in Part Three. Whatever your choice, enjoy the journey! THE TURNING POINT The idea started on New Year’s Day in 1980, when my boyfriend (now my
