摘要
本文用自旋捕捉技术与ESR相结合的方法研究了6种脂肪胺电解氧化过程中产生的瞬态自由基。结果表明,阳极上脂肪胺氧化产生相应的正离子自由基,而后脱去α-C上的质子得到一碳中心自由基,此自由基能被捕捉剂PBN所捕获;阴极上发生H^+还原反应,所得的氢原子也可被PBN捕获。
Active free radicals formed in the process of electrolysis-oxidation of some alkylamine (trimethylamine, triethylamine, tri-n-propylamine, tri-i-octylamine, diethylamine and hexahydropy-ridine) were studied by the combination of ESR spectrometry and spin trapping technique. The results show that not only the secondary a-C center radical formed in the anode chamber but also cathodic H atom can be trapped by spin trapping reagent phenyl-t-butyl nitrone.
