摘要：
A method of decomposing halogenated aromatic compounds safely without fail, which comprises bringing a solution of a halogenated aromatic compound in a hot-alkali-resistant polar solvent into contact with an alkaline substance at about 100 to about 300 DEG C to decompose the aromatic compound and removing the salt and alkaline substance precipitated in the solvent to recycle the used solvent.
