  • Chlorofluorocarbons (CFCs)

    716 Words  | 3 Pages

    Chlorofluorocarbons (CFCs) Chlorofluorocarbons (CFCs) (also known as Freon) are non-toxic, non-flammable and non-carcinogenic. They contain fluorine atoms, carbon atoms and chlorine atoms. The 5 main CFCs include CFC-11 (trichlorofluoromethane - CFCl3), CFC-12 (dichloro-difluoromethane - CF2Cl2), CFC-113 (trichloro-trifluoroethane - C2F3Cl3), CFC-114 (dichloro-tetrfluoroethane - C2F4Cl2), and CFC-115 (chloropentafluoroethane - C2F5Cl). CFCs are widely used as coolants in refrigeration and

  • CFC (Chlorofluorocarbons)

    1036 Words  | 5 Pages

    CFC The beginning of the CFC(chlorofluorocarbons) era started in 1928, when CFC' were invented by a Du Pont chemist. CFC' were best known as "freons" and became famous as a safe, nonflammable refrigerant. It's invention became a great triumph when Freon took the place of sulfur dioxide or ammonia which was used as the working liquid in refrigerators. It eventually became widely used in automobile air conditioners and nontoxic propellants in aerosol cans. It's insulating properties also was used

  • Chlorofluorocarbon Essay

    747 Words  | 3 Pages

    CFC Introduction: The organic compound Chlorofluorocarbon is known as CFC. This compound is made of chlorine fluorine and carbon only. CFC is in the group volatile organic compound. The CFC was first invented or made in 1928. The main purpose of CFC was to uses as refrigerants for refrigeration. Freon is the trade name of CFC .There are some main reasons behind the wide use of CFC. Non-toxic and flammability were the main reason. Around in 1960s the use of CFC increases among the developing nations

  • Global Warming and Chlorofluorocarbons (CFCs)

    1483 Words  | 6 Pages

    Global Warming and Chlorofluorocarbons (CFCs) Chlorofluorocarbons are non-toxic, non-flammable chemicals that are mainly used in the manufacturing of aerosols, blowing agents for foams and packing materials, as solvents, and as refrigerants. They are classified as Halocarbons, a class of compounds that contain carbon and halogen atoms, and are amongst a group of substances called “greenhouse gases”. They eat away at our ozone and raise the temperature of our planet significantly, causing detrimental

  • Chlorofluorocarbons (CFCs)

    1185 Words  | 5 Pages

    Chloroflourocarbons Chloroflourocarbons were discovered in the 1920's by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non- toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and trichloromonoflouromethane (CFC-11). In both compounds, different amounts of chlorine and fluorine are combined with methane, which is a combination

  • Chlorofluorocarbons Essay

    1051 Words  | 5 Pages

    Chlorofluorocarbons [CFCs], commonly known as Freon, are a type of organic compounds that are made up of carbon, chlorine, and fluorine atoms. Their significant properties include low volatility of approximately 0℃, together with being tasteless, odourless, non-flammable, nontoxic, and chemically stable. They have supported the society for years through the form of a refrigerant, a solvent and a propellant. Moreover, they have contributed to the industrialization of nations, especially during the

    biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found that human-made chlorofluorocarbons used for making foam, cleaning fluids, refrigerants, and repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for several decades due to their long tropospheric lifetimes. These compounds are carried into the stratosphere where they undergo hundreds of catalytic

  • Global Warming

    680 Words  | 3 Pages

    Although global warming is as complicated as we make it, so why not start with a different outlook. In the year 2050 I predict most of the world to be under water. The reason relate to the shrinking ice sheets, the Ozone layer and the ozone hole enlarging, also the recent higher sea levels. With certain activities we do on a daily basis we actually control these processes. Some of our activities we do on a daily basis can affect these processes faster. We as humans should change our ways, the city

  • Essay On Hairspray

    1030 Words  | 5 Pages

    Quaternium-52, Benzyl Salicylate, Limonene, Hexyl Cinnamal, Linalool. Hair spray contain many VOCs (volatile organic compounds) which cause serious damage to the ozone such as ozone depletion. These compounds, including methane as known as CFC (Chlorofluorocarbon), have been serious factors causing global warming. CFC was developed in the 1930s under the trade name Freon. “CFC was supposed to be wonder chemicals since they are nontoxic, nonflammable, don't react with any common chemicals, and thus were

  • Obstacles To Pollution Prevention

    in existing technology. Incremental changes include substituting one or two steps in a production process or relationship changes between production steps. One example of incremental changes that was provided by the author was eliminating chlorofluorocarbons and saving energy by replacing a refrigeration process with a heath exchanger that can exploit waste cooling from another part of the process. There are three critical decision-making stages for incremental changes; identifying a pollution
