Abstract
The possibilities of the application of mechanochemical method for performing dechlorination process with chlorinated aromatic compounds and polyvinylchloride are considered. On the basis of spectral investigations, we proposed possible mechanism and the composition of products of mechanochemical dechlorination of chlorinated aromatic compounds. Mechanochemical transformation of hexachlorobenzene, 1,4-dichlorobenzene and octachloronaphthalene, o-nitrochlorobenzene in the presence of alkaline agents proceeds with the formation of phenols and naphthols. This process can be represented as nucleophilic substitution in the aromatic ring. It is demonstrated that the intensity of mechanical action affects the relations between the main products of o-nitrochlorobenzene transformation. Under high-intensive mechanical action, the major product of the interaction of o-nitrochlorobenzene is 2-nitro-3-chlorophenol; under soft conditions, it is o-nitrophenol.
