摘要：
The method of CHNS-analysis in combination with P-31 NMR and UV-VIZ spectroscopy was used to study polyoxometallates and ionic liquids as components of liquid-phase catalytic systems. The composition of imidazolium and TBA salts of tungstophosphate anions active in the olefin oxidation with H2O2 was determined. A method for quantification of [BMIm]Br, Bu4NBr, Bu4NHSO4 in solutions using the CHNS -analysis is proposed. The capabilities of the technique with applying ionic liquids to an inert porous support are evaluated. Using the obtained results, the effect of ionic liquids in combination with a Pt/C catalyst and H3PMo12O40 heteropolyacid in the oxidation of cyclohexane with O-2-H-2 gas mixture was determined.
