A halogen scavenger contains as an effective ingredient an aromatic compound which has a resonance-effect-relying electron donating group as a substituent. The aromatic compound is constituted, for example, by an aromatic ring such as a substituted or unsubstituted benzene, naphthalene, anthracene and pyridine ring, and at least one group (a resonance-effect-relying electron donating group) which contains a lone-pair-containing hetero atom, such as an oxygen, sulfur or nitrogen atom, adjacent to the aromatic ring.
卤素清除剂的有效成分是一种芳香族化合物,其取代基具有依赖共振效应的电子捐献基团。例如,芳香族化合物由一个芳香环(如取代或未取代的苯、萘、蒽和吡啶环)和至少一个基团(依赖共振效应的电子供体基团)构成,该基团包含一个与芳香环相邻的含孤对杂原子(如氧原子、硫原子或氮原子)。
