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.
Freon, (trademark), any of several simple fluorinated aliphatic organic compounds that are used in commerce and industry. In addition to fluorine and carbon, Freons often contain hydrogen, chlorine, or bromine.
Fluorocarbons are chemical compounds with carbon-fluorine bonds. Compounds that contain many C-F bonds often have distinctive properties, e.g., enhanced [clarification needed] stability, volatility, and hydrophobicity. Several fluorocarbons and their derivatives are commercial polymers, refrigerants, drugs, and anesthetics. [1]
Ninety is added to the CFC number, abc, to give as a result a number, xyz, that corresponds to the Carbon-Hydrogen-Fluorine (CHF) composition. If the carbon atoms are not saturated then additional chlorine atoms are required.
The trademark Freon refers to any of several gaseous chlorofluorocarbons, CFCs, with the general formula CF x Cl 4−x or C 2 F x Cl 6−x . Due to their physical and chemical properties, these CFCs became the compounds of choice as propellants and refrigerants, substituting for the toxic and flammable sulfur dioxide and ammonia materials used ...
8 paź 2024 · 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 &.
17 lis 2023 · 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.
