Abstract

Abstract: 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 ESRspectrometry and spin trapping technique. The results show that not only the secondary a-Ccenter radical formed in the anode chamber but also cathodic H atom can be trapped by spin trapping reagent phenyl-t-butyl nitrone.

Key words: Radicals, Alkylamine, Electrolysis-oxidation, ESR, Spin trapping
