halogengáz

Halogengáz, also known as halogenated gas, refers to a group of chemical compounds that contain one or more halogen atoms (fluorine, chlorine, bromine, iodine, or astatine) bonded to carbon or hydrogen. These gases are widely used in various industrial applications due to their unique properties, such as their ability to act as refrigerants, solvents, and propellants. Halogengáz are classified into several categories based on the type of halogen and the number of carbon atoms in the molecule. For example, chlorofluorocarbons (CFCs) are a type of halogengáz that contain chlorine and fluorine atoms. These compounds were once commonly used in refrigeration and air conditioning systems but have since been phased out due to their significant contribution to ozone depletion. Other types of halogengáz include hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs), each with its own set of industrial uses and environmental implications. The production and use of halogengáz are regulated by international agreements, such as the Montreal Protocol, to mitigate their environmental impact.
