Abstract: | Summary The surface properties of complex adsorbents prepared through the pyrolysis of benzyl and n-heptyl alcohols and their mixtures
on the surface of silica gel were investigated. The reactions were carried out in an autoclave at 500°C. A series of adsorbents
having different porous structure, chemical nature of the adsorption centers and their topography were obtained. The best
resolution of different mixtures was obtained by the carbon-silica adsorbent prepared through the pyrolysis of n-heptanol. |
