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).

2017年4月18日 · Each chlorine atom would react immediately with an ozone molecule, setting off a chain reaction that would destroy thousands of ozone molecules. In their paper, they estimated that if CFC use was banned immediately, ozone loss would go on for years. If CFC production continued, however, ozone loss would be even greater.

氯氟碳化合物能夠溶解 油 脂，故被用作 電子零件 及 金屬 用品的 清潔劑。 用作 冷凍劑 的氯氟碳化合物，稱為 氟利昂。 氟利昂氣化時吸收大量 內能，令附近環境變冷，所以成為冷藏器（例如 冰箱 及 空調）的冷凍劑。 在製造 發泡膠 的過程中，氯氟碳化合物被混合於 塑膠 中，成為發泡膠的气泡。 氯氟碳化合物也被加進 汽油 中，防止汽油因低溫而 凝結。 部份使用後的氯氟碳化合物上升到同溫層（平流層 底部）。 由於其低活躍性、低生物降解性及不溶於水，氯氟碳化合物很難 …

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.

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 …

Chlorofluorocarbons (CFCs) are man-made compounds consisting of chlorine, fluorine, and carbon. You might have heard questions like what is CFC or what are CFCs used for? Well, they were once widely celebrated for their role in refrigeration, air conditioning, and aerosol sprays.

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2月13日 · 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. And while they’ve never been nearly as abundant as CO 2, these compounds are much more potent at trapping heat in the atmosphere.

2021年8月18日 · Chlorofluorocarbons (CFCs) are gaseous chemicals that have been widely used over the past century since their creation in 1928. These products were investigated and their properties were shown to endanger public health by destroying the ozone layer, which is why its use was prohibited.

Chlorofluorocarbons (CFCs) are synthetic organic compounds that contain chlorine and fluorine. They are known for their ability to deplete stratospheric ozone and were eliminated from use under the Montreal Protocol. CFCs are clear, colorless liquids or gases with a slight etherlike odor at high concentrations.
