Halogenated solvents are chemical compounds that have halogen atoms. Several of these types of compounds are found in homes and even used everyday, such as iodine and chlorine. These compounds can also be combined with carbon atoms to make new compounds and mixtures.
When the carbon atoms are added, the compounds become covalent halies, or halocarbons. One of the most familiar types of these compounds are referred to as CFCs. These are often best known from the movement to take these chemicals out of things like hairspray and other types of sprays that use them as propellants. These are also commonly known as Freon and used in types of refrigeration. These chemicals have been slowly removed from production because of the harmful by-products they create and their contribution to the greenhouse effect.
