Title:
METHOD FOR DECOMPOSING HARDLY DECOMPOSABLE ORGANIC HALOGEN COMPOUND
Document Type and Number:
Japanese Patent JP2004115411
Kind Code:
A
Abstract:
To provide a method whereby a hardly decomposable solid organic halogen compound such as a persistent agrochemical [e.g. hexachlorocyclohexane (BHC) or hexachlorobenzene (HCB)] is properly decomposed though the method uses an alkali metal dispersion.
This decomposition method comprises reacting the hardly decomposable organic halogen compound dissolved in a solvent comprising an aromatic or alicyclic hydrocarbon boiling at 80 to 200°C with the alkali metal dispersion prepared by dispersing an alkali metal in a dispersion medium comprising an aromatic hydrocarbon having a boiling point higher than the melting point of the alkali metal, thus dehalogenating the hardly decomposable organic halogen compound.
