Фреон Хладогент R-1234YF: продажа, цена в Китае
HFO-1234yf is a hydrofluoroolefin with the formula CH2=CFCF3. It has been proposed as a replacement for R134a as a refrigerant in automobile air conditioners. HFO-1234yf is the first in a new class of refrigerants acquiring a global warming potential (GWP) rating one 335th that of R134a (and only 4 times higher than carbon dioxide, which can also be used as a refrigerant but which has properties significantly different from those of R134a, especially requiring operation at around 5 times higher pressure) and an atmospheric lifetime of about 400 times shorter. It was developed to meet the European directive 2006/40/EC that went into effect in 2011 requiring that all new car platforms for sale in Europe use a refrigerant in its AC system with GWP below 150.NamesIUPAC name2,3,3,3-tetrafluoroprop-1-eneOther namesHFO-1234yf; R1234yf; R-1234yf; 2,3,3,3-TetrafluoropropyleneIdentifiersCAS Number754-12-1 ChemSpider2057041 Jmol 3D modelInteractive imageInteractive imagePropertiesChemical formulaC3H2F4Molar mass114 g/molAppearancecolorless gasDensity1.1 g/cm3 at 25 °C (liquid); 4, air = 1 (gas)Boiling point−30 °C (−22 °F; 243 K)Solubility in water198.2 mg/l at 24 °C, 92/69/EEC, A.6log P2.15, n-octanol/water, 92/69/EEC, A.8Vapor pressure6,067 hPa at 21.1 °C; 14,203 hPa at 54.4 °CFotech International - one of the largest and best refrigerant r1234yf to replace refrigerant r134a manufacturers and suppliers in China, is committed to producing customer driven refrigerant r1234yf to replace refrigerant r134a of high quality.
