They are also commonly known by the DuPont brand name Freon.CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. A blend that contains a CFC and any other product is still considered a CFC refrigerant.Addendum a to Standard 147-2019. Modify Section 9.2 to include new subsection 9.2.3.1 as shown. 9.2.3.1 Storage of Flammable Refrigerants. Storage of Class 2L, 2, and 3 refrigerants shall comply with NFPA 55, Compressed Gases and Cryogenic Fluids Code, and International Fire Code (IFC) Chapter 58, “Flammable Gases and …The halogen source gases, often referred to as ozone-depleting substances (ODSs), include manufactured chemicals released to the atmosphere in a variety of applications, such as refrigeration, air conditioning, and foam blowing. Chlorofluorocarbons (CFCs) are an important example of chlorinecontaining gases.

A DuPont R-134a refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC refrigerants to ozone depletion and that of HFC ...For example, halogen-containing polymers have the potential to be more durable, chemically resistant, and electronically conductive, making them valuable in various industrial applications. The future applications of halogens in drug development, sustainable energy solutions, and advanced materials hold promise for advancing … ….

Halogenated hydrocarbons are organic compounds consisting of C-C, C-H and C-X bonds where. X is a halogen atom (F, Cl, Br, I). Carbon has a valence of four and thus requires four electrons or bonds to complete its octet in the neutral state. Hydrogen has a valence of one and thus requires a single electron or bond to complete its "duet" in ...organohalogen compound, any of a class of organic compounds that contain at least one halogen ( fluorine [F], chlorine [Cl], bromine [Br], or iodine [I]) bonded to carbon. They are subdivided into alkyl, vinylic, aryl, and acyl halides. In alkyl halides all four bonds to the carbon that bears the halogen are single bonds; in vinylic halides the ...

In addition, some air conditioning and refrigeration systems use non-halogenated refrigerants such as ammonia, carbon dioxide (CO 2), propane, or isobu tane. Also, some fire suppression equipment, which historically used ozone-depleting halons, use carbon dioxide (CO 2), inert gases, and other substances.throughout this book to include all the common refrigerants.
