微波放电活化氮及氩与丙酮、丁酮反应机理的ESR/GC研究

ESR/GC STUDIES ON THE REACTION MECHANISM OF ACETONE AND METHYLETHYL KETONE WITH ACTIVATED NITROGEN AND ARGON IN MICROWAVE DISCHARGE SYSTEMS

用电子自旋共振(ESR)/气相色谱(GC)相结合的方法,研究了在氮或氧气存在下进行徽波放电中(?)类分子的反应过程.由ESR和GC平行检测结果表明:主要过程是经由徽波放电面使N_2或Ar活化后酮分子a或激发态子后,与酮分子进行碰撞传能而生成激以酮分子.并立即进一步分解.■而产生自由基反应.

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.
