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).

2023年2月13日 · Carbon dioxide (CO 2) is the most well-known and significant greenhouse gas causing climate change. But there are others, including methane, nitrous oxide—and chlorofluorocarbons (CFCs). CFCs were developed in the late 1920s to replace toxic compounds used in refrigeration and air conditioning; they have also been used in aerosols and as solvents.

氯氟碳化合物（Chlorofluorocarbons，简称 CFCs），又称氟氯烃，是一类只含有氯、氟和碳的有机物。 代表性物质是 三氯氟甲烷。 属于 氟利昂 （Freons）中的一类物质。 用作制冷剂、压缩喷雾喷射剂、发泡剂。 因消耗大气层中的 臭氧 而引起世界各国的重视。 《蒙特利尔议定书》要求签署国逐步减少使用并最终于 1996 年停止使用氯氟碳化合物。 [1] 氯氟碳化合物（Chlorofluorocarbons，简称 CFCs），又称氟氯烃，是一类只含有氯、氟和碳的有机物，包 …

2025年2月17日 · Chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorines, they are called hydrochlorofluorocarbons, or HCFCs. CFCs are also called Freons, a trademark of the E.I. du Pont de Nemours &

The chlorofluorocarbon definition is simple: they’re stable, non-flammable, and non-toxic gases or liquids. These properties made them a favorite for various industrial applications. Examples of chlorofluorocarbons include CFC-11 and CFC-12, commonly found in older refrigerators and aerosol products. Where Do CFCs Come From?

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms.

2017年4月18日 · Rowland, a professor of chemistry at the University of California, Irvine, and Molina, a postdoctoral fellow in Rowland’s laboratory, had shown that chlorofluorocarbons—CFCs—could destroy ozone, a molecule made up of three oxygen atoms, O 3, in Earth’s stratosphere.

Chlorofluorocarbons (CFC) are gases used for various purposes including solvents, refrigerants and aerosol sprays. They are organic chemicals and contain carbon, (sometimes hydrogen,) chlorine, and fluorine.

2023年4月3日 · Chlorofluorocarbons (CFCs) are industrially produced compounds that were commonly used as refrigerants, aerosol propellants, solvents and foam-blowing agents. An...

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.
