    The electro-reductive transformation of halogenated benzenes

  • Original language description

    DEMS is a type of experimental technique, which makes possible a direct MS investigation of electro-sorption, electro-oxidation and electro-hydrogenation processes. The experimental set-up consists of a PC controlled mass spectrometer TRIO 1000 (FinniganMAT, Fisons Instruments, USA) connected with an electrochemical cell made from PTFE connected to the direct inlet of the mass spectrometer. Polycrystalline Pt disc controlled by Autolab PGSTAT100 (Ecochemie, The Netherlands) served as working electrode.The results of measurement are presented as plots of ion current of parent-hydrocarbons and hydrogenation products as potential function of working electrode. Simultaneously with ion current-potential curves (MSCV - curves) the faradaic current-potential curves were acquired as well. It is shown that comparing to direct electro-reduction of C-halogen bond in nonaqueous medium, in acid water solution the dehalogenation even C-fluorine bond proceeds at rather low potential.

    Elektroreduktivní transformace halogenbenzenů (poster)

  • Czech description

    DEMS je experimentální technika spojující elektrochemické metody s hmotnostním spektrometrem on-line. Naše zařízení se sestává z hmotnostního spektrometru Trio 1000(Finnigan, USA) a potenciostatu Autolab 100 (Ecochemie, The Netherlands)s polyktrystalickou platinovou elektrodou. Je ukázáno, že ve srovnání s nevodným prostředím ve vodném prostředí dehalogenace halogenbenzenů včetně fluorbenzenu probíhá při podstatně pozitivnějších potenciálech. Výsledky jsou prezentovány jako křivky iontových proudů-potenciál (MSCV) a faradaický proud-potenciál registrované souběžně.
