Tetrachloro-1,2-difluoroethane is a chlorofluorocarbon known as Freon 112, CFC-112 or R-112. It has a symmetrical structure CCl 2 FCCl 2 F and so can be called symmetrical tetrachlorodifluoroethane. "Symmetrical" may also be abbreviated to "s-" or "sym-". In contrast an asymmetrical isomer has formula CCl 3 CClF 2.
The CFC finances commodity development projects in developing states. The CFC was established in 1989. It was set up by a 1980 multilateral treaty known as the Agreement establishing the Common Fund for Commodities. As of June 2017, there are 110 parties to the Agreement and thus to the CFC.
It is a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant. In compliance with the Montreal Protocol , its manufacture was banned in developed countries (non-article 5 countries) in 1996, and in developing countries (Article 5 countries) in 2010 out of concerns about its damaging effect on the ozone layer ...
The Kigali Amendment to the Montreal Protocol is an international agreement to gradually reduce the consumption and production of hydrofluorocarbons (HFCs). It is a legally binding agreement designed to create rights and obligations in international law.
2,2-Dichloro-1,1,1-trifluoroethane or HCFC-123 is considered as an alternative to CFC-11 in low pressure refrigeration and HVAC systems, and should not be used in foam blowing processes or solvent applications.
The solubility measurements of CFC-11 and CFC-12 have been previously measured by Warner and Weiss [73] Additionally, the solubility measurement of CFC-113 was measured by Bu and Warner [74] and SF 6 by Wanninkhof et al. [75] and Bullister et al. [76] Theses authors mentioned above have expressed the solubility (F) at a total pressure of 1 atm as:
