Process for decreasing the halogen content of polyhalogenated aromatics |
摘要 |
When the halogen content of polyhalogenated aromatics is decreased by reaction with monohalogenated and/or non-halogenated aromatics in the gas phase, good yields and significantly improved catalyst service lives are achieved if the reaction is carried out in the presence of a catalyst and in the presence of a hydrogen halide.
