| 摘 要： | 用电子自旋共振(ESR)/气相色谱(GC)相结合的方法,研究了在氮或氧氢气存在下进行微波放电中酮类分子的反应过程.由ESR和GC平行检测结果表明:主要过程是经由微波放电面使N2或Ar活化后形成激发态分子或激发态离子后,与酮分子进行碰撞传能而生成激发态酮分子,并立即进一步分解,继而产生自由基反应.

| Abstract: | The reaction processes of ketones in the presence of Nitrogen or Argon by microwave discharge have been studied with the combined technique of ESR and gas chromatography. The results show that free radical reactions initiated by excited N2 (Ar) or N2 (Ar ), which were formed in microwave discharge, are the fundamental processes. Reaction mechanisms are discussed. |
