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).

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，包括 三氯氟甲烷 、 二氯二氟甲烷 、 二氯四氟乙烷 等物质。 常温下，氯氟碳化合物是无色气体或液体，易挥发（高 蒸气压，低 沸点），化学性质稳定，不易燃，无毒。 属于 挥发性有机物。 从气态到液态和从液态到气态的过程都很容易实现。 另外，还具有 密度 高、 粘度 低、 表面张力 低、 折射率 低等特点。 [1-3] 氯氟碳化合物属于 氟利昂 （Freons），最早于 20 世纪 30 …

氯氟烃由一群以 托马斯·米基利 为首的 美國 科學家 於1928年人工合成，用作冷藏器的 冷凍劑 （雪種），因為過往的冷凍劑（例如 氨 及 二氧化硫）都易燃或有毒。 其後，氯氟碳化合物被廣泛使用，直至20世紀末 科學家 意識到氯氟碳化合物的害處為止。 氯氟碳化合物由一個 烷烴 經 鹵化反應 （自由基 取代反應）與氟、氯分子結合而成，而烷烴的氫 原子 會被氟或氯原子所取代；仍有氫原子未被取代的則稱為含氫氯氟烴（HCFCs）。 由於氯氟碳化合物無味、無易燃性、無毒 …

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.

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 &

Yes, chlorofluorocarbons are indeed greenhouse gases, but their impact goes beyond trapping heat. Unlike carbon dioxide or methane, CFCs don’t just warm the planet. They also attack the ozone layer, the shield that protects us from harmful …

2023年11月17日 · Chlorofluorocarbons (CFCs) are non-toxic, non-flammable chemicals composed of carbon, chlorine, and fluorine, with the term CFC originating from these constituent elements. They have been used in items such as aerosol sprays, foam-blowing agents, solvents, and refrigerants.

2018年4月10日 · Contact with and inhalation of chlorofluorocarbons can cause damage to the neural and immune system. CFCs can also damage the eyes, and by degrading the ozone layer, cause higher incidences of skin cancer.

Chlorofluorocarbons (CFCs) are artificially made chemical compounds used as refrigerants, cleaning solvents, aerosol propellants, and blowing agents for foam packaging in many commercial applications. They typically consist of chlorine, fluorine, carbon, and hydrogen. Freon ®, a trade name, is often used to refer to them.

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.
