二氯二氟甲烷，又名氟利昂-12，是一种有机化合物，化学式为CCl 2 F 2 ，可用作制冷剂、灭火剂、杀虫剂和喷射剂，也是氟树脂的原料。

Dichlorodifluoromethane (R-12) is a colorless gas popularly known by the genericized brand name Freon (as Freon-12). It is a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant.

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. The most common example is dichlorodifluoromethane (R-12).

Inhaled CFC-12 rapidly appeared in blood, bile, cerebrospinal fluid, and urine of anesthetized rabbits and dogs. Unanesthetized dogs exposed to 1000 to 100,000 ppm for 10 min showed rapid rise in blood concentrations of CFC-12 during the first 3 to 5 minutes, which was paralleled by a rapid decline for first 5 min after exposure.

2024年12月30日 · CFC-12 (also known by the trade name Freon or Freon-12) is an ozone-depleting refrigerant and potent greenhouse gas that was widely used in air conditioners for automobiles and trucks for over 30 years, up until the mid-1990s.

2024年6月12日 · Dichlorodifluoromethane (CFC-12) is an ozone-depleting substance and potent greenhouse gas, which was required to be phased out after 2010 under the Montreal Protocol. CFC-12 emissions need to be quantitatively traced. However, estimates of CFC-12 emissions in China based on atmospheric inversions are unavailable after 2010.

2025年3月31日 · Use of the ozone-depleting refrigerant, chlorofluorocarbon (CFC)-12, in new motor vehicle air conditioning (MVAC) systems ended in the mid-1990s in the United States. Since 1994, the most common refrigerant used in MVAC systems has …
