The structure of benzene and water adsorption complexes on a complex carbon-silica adsorbent (carbosil) surface was studied by H-1 NMR spectroscopy. The adsorbent was obtained by pyrolysis of CH2Cl2 at 500 degrees C on the surface of pyrogeneous silica (Aerosil-300). Disordered fragments of graphite planes were found to be adsorption centers for benzene molecules. Water molecules are sorbed on the residual hydroxyl groups of silica as well as at oxygen-containing adsorption centers of the carbon material. The thicknesses of the solvation shells of benzene and water of initial aerosil and carbon black particles were determined.
