Реферат: Alumina modification with sulfates was found to result in a gradual increase of the concentration of electron-acceptor sites characterized using the formation of radical cations from aromatic molecules with different ionization potentials. The strongest electron-acceptor sites tested with toluene immediately after adsorption were only detected with a concentration of SO3 not less than 4%. The weakest sites tested with perylene presented on the surface of all the samples, with their concentration on 12% SO3 sample being 3×1019 g -1. Chlorination only led to minor growth of the concentration of the weak sites. Recommendations on the use of spin probes for testing electron-acceptor sites with different strength are suggested. A mechanism of the polycondensation of aromatic probes on the surface electron-acceptor sites explaining experimental results and possible structures of such sites were proposed
