PP-V-10Electrocatalysis in Ionic Liquid Using Organic MediatorsOkhlobystin А.О. 1 , Storogenko V.N. 1 , Okhlobystina A.V. 1 , Koldaeva Yu.Yu. 1 ,Berberova N.T. 21 Astrakhan State Technical University, Astrakhan, Russia2 Southern Scientific Center, Russian Academy of Sciences, Rostov-on-Don, Russiaionradical@gmail.comIn this work we used one of the special properties of ionic liquids - high electroconductivityand wide polarization potential value interval [1]. We investigated electrocatalytic thioloxidation by different electromediators in the ionic liquid without supplemental electrolyteapplication. Aromatic amines (tri-p-tholylamine, tri-p-bromphenyl-amine, 2,2`,4,4`tetramethoxiphenylamine,N,N,N`,N`-tetramethyl-1,4-phenylenediamine, phenoxazine) wereused as electromediators. Aromatic amines were brought in minimum amount and allowed tominimize power inputs in 0.5-0.8V [2]. Consequent electrolysis led to dibutyldisulfideformation thereupon dibutylsulfide (1,7V) as products of one-electron oxidation,fragmentation and dimerization of thiols. Product identification was performed by cyclicvoltammetry, IR-spectroscopy and gas chromatography.The study was financially supported by RFBR (12-03-00513а), grant of the President of RF(МК-923.2012.3), federal special-purpose programme “Scientific and pedagogical personnelof innovative Russia” 2009-2013 (ГК № 16.740.11.0594).References:[1] L.
