METHOD OF
DETOXIFICATION OF POLYORGANOCHLORINE WASTE
FIELD: organochlorine compounds, ecology.
SUBSTANCE: invention relates to methods of
detoxification of polyorganochlorine waste containing high-boiling and
resin-like substances where polychlorobenzenes are the main components. Method
is carried out by hydrogenation of waste with molecular hydrogen in an aqueous
solution of alkaline reagent in the presence of palladium on carrier as a
catalyst at increased temperature and pressure. Hydrogenation reaction is
carried out in biphase system water-hydrocarbon. A mixture of benzene and
cyclohexane is used as hydrocarbon source. The ratio of hydrocarbon and
polyorganochlorine waste to be detoxificated is 0.5-3 ml of hydrocarbon per 1 g
of polyorganochlorine waste to be detoxificated. Sodium hydroxide 10-20% an
aqueous solution is used as an alkaline reagent. Process is performed at 60-130
C under pressure 10-50 atm. Method provides elimination of hardly utilizable
waste.
EFFECT: improved method of detoxification,
enhanced effectiveness of process of detoxification of polyorganochlorine waste.
