In the United States, the regulation of F-gases falls under the authority of the Environmental Protection Agency's overall attempts to combat greenhouse gases. [7] The United States has put forward a joint proposal with Mexico and the Federated States of Micronesia for a phase-down of HFCs by 2030. The American Innovation and Manufacturing Act ...
Their atmospheric concentrations and contribution to anthropogenic greenhouse gas emissions are rapidly increasing --- consumption rose from near zero in 1990 to 1.2 billion tons of carbon dioxide equivalent in 2010 [4]--- causing international concern about their radiative forcing.
In open atmosphere however, HFO-1234ze actually forms HFC-23 as one of its secondary atmospheric breakdown products. HFC-23 is a very potent greenhouse gas with a GWP100 of 14,800. This makes the secondary GWP of R-1234ze in the range of 1,400±700 considering the amount of HFC-23 which may form from HFO-1234ze in the atmosphere.
Hydrophobic fluorinated ionic liquids, such as organic salts of bistriflimide or hexafluorophosphate, can form phases that are insoluble in both water and organic solvents, producing multiphasic liquids. Fluorine-containing compounds are often featured in noncoordinating or weakly coordinating anions.
1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
Sulfuryl fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2. It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride , being resistant to hydrolysis even up to 150 °C. [ 3 ]
Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...
Within organofluorides, refrigerant gases are still the dominant segment, consuming about 80% of HF. Even though chlorofluorocarbons are widely banned, the replacement refrigerants are often other fluorinated molecules. Fluoropolymers are less than one quarter the size of refrigerant gases in terms of fluorine usage, but are growing faster.
