Abstract

The reactions of surface hydroxyl groups of pyrogenic silica, Aerosil with chromium oxychloride and trichlorosilane are satisfactorily described at the initial sections by the first and second order equations. These reactions were used as an example and it was shown that the kinetic method is applicable for determining the concentration of OH groups on the SiO2 surface.
