Method of decomposing halogenated aromatic compound with alkaline substance

摘要

In the method of decomposing halogenated aromatic compounds, halogenated aromatic compounds and alkalis are contacted in a non-proton polar solvent at a temperature ranging from about 150 DEG C to about 300 DEG C for about 1 to about 10 hours. The blending ratio of alkalis with respect to the whole reaction system when the reaction starts is set at 5,000 mg/kg or more. Whereby, the halogenated aromatic compounds can be decomposed certainly and safely.
