Abstract

Polyhalogenated organic compounds, such as polychlorinated dibenzodioxines, dibenzofurans, biphenyls, biphenyl ethers, phenols, benzenes and cyclohexanes as well as chlorofluorohydrocarbons are destroyed by reaction with a surplus of strongly basic hydrocarbon-soluble, strongly basic lithium compounds in an inert solvent at reaction temperatures from 0.degree. to 200.degree.
