摘要：

A comparative study of composites based on imidazolium phosphomolybdates of the SILP type of catalysts for peroxide oxidative desulfurization was performed by mass spectrometry and other physicochemical methods, in particular, XPS (X-ray photoelectron spectroscopy). An analysis of the data obtained revealed partial destruction of heteropolyanions during the synthesis of heterogeneous samples. The results of mass spectrometric measurements are well correlated with the XPS data, indicating the possibility of using mass spectrometry (MS) in the surface-activated laser desorption/ionization (SALDI) technique for characterization of these composites. The results of the analysis of the desulfurization rate showed the important role of the products of partial destruction of heteropolyacid anions in the catalysis of the process.
