- Аннотация: Abstract The adsorption properties of two samples of zirconyl-containing silica gels derived from zirconium oxychloride, polyetoxysiloxane oligomer 3% ZrOCl2/SiO2 (composite 1) and tetraetoxysilane 5% ZrOCl2/SiO2 (composite 2) were investigated by gas chromatography at low surface coverages. n-Alkanes and n-alkenes (C6–C8), C6H6 were used as test adsorbates, along with polar compounds whose molecules had different donor-acceptor interaction abilities. The dispersion and specific (electron-donor and electronacceptor) components of the energy of intermolecular interactions for the studied systems were determined from the experimental data on chromatographic retention. It was shown that composite 2 had a higher dispersion potential and higher surface energy characteristics of the surface’s electron-donating and electronacceptor centers, as compared to composite 1.
