hydrofluoroolefiner
Hydrofluoroolefins, often abbreviated as HFOs, are a class of refrigerants and blowing agents that have gained prominence as replacements for older hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs). Their key characteristic is a carbon-carbon double bond, which contributes to their very low global warming potential (GWP). This double bond makes them susceptible to rapid breakdown in the atmosphere, typically within days, significantly reducing their persistence and thus their impact on climate change compared to HFCs, which can persist for decades or even centuries.
HFOs are synthesized through various chemical processes, often involving the dehydrofluorination of saturated hydrofluorocarbons or fluorination
However, HFOs also present certain considerations. While their flammability is generally lower than that of hydrocarbons,
