Electro-oxidation of benzyl alcohol to benzaldehyde in supercritical CO2 with ionic liquid

Measurements of the double layer capacitance for electrodes in supercritical CO2/acetonitrile electrolytes

“…Nevertheless the charge distribution is crucial for understanding the kinetics of redox reactions and electrodeposition studies. Electrochemistry in supercritical fluids has received attention for applications in electroanalysis [7], electrosynthesis [8][9][10], electrochemical reduction of CO 2 [11,12], electrodeposition [13][14][15], and for energy conversion [16]. Abbott and Eardley [17] appear to be the first authors to report double layer capacitance measurements in a polar supercritical fluid.…”

The electrochemical oxidation of toluene catalysed by Co(ii) in N-butyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide

“…Since some of the RTILs have moderate conductivity, the electro-chemical oxidation of the volatile organic compounds dissolved in RTILs appears feasible for incorporating hydrophilic functional groups and studies on direct electrochemical oxidation of organic compounds have been reported in ionic liquid media. 16,17 But there has been no investigation on the electro-oxidation of hydrophobic organic solvents such as toluene catalysed by a metal ion oxidant such as Co(II) or Ag(I) which have been used previously by many researchers for the electro-oxidation and electrochemical mineralization of target organic compounds in aqueous media for organic synthesis and environmental pollutant degradation applications, respectively. [18][19][20][21] In the present work we have investigated the cyclic voltammetric behaviour of Co(II) ions dissolved in the room temperature ionic liquid N-butyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide ([bmpyr] + [Ntf 2 ] À ) at various scan rates and temperatures.…”
