Abstract

Investigation of catalytic activity of molten eutecticmixtures of alkali metal hydroxides and carbonates with and without addition of active components: V2O5, CuO, and NaNO3 with the reaction of deep oxidation of γ-C6H6Cl6 (lindane, an insecticideof contact, enteric, and fumigant action) in relation to temperature, catalyst load, and О2 : γ-C6H6Cl6 molar ratio relative to stoichiometry in a closed system was carried out. It is shown that the highest activity, among the catalytic systems studied, in the reaction of deep oxidation of lindane is exhibited by molten catalysts based on a eutectic mixture of alkali metal carbonates with addition of active components V2O5 and CuO.
