Distribution of silica surface active sites and examination of their surface heterogeneity have been assessed by study of their reactivity towards alcohols, water and polyamines, and by characterization of the initial and modified samples. The results obtained provided valuable informations as for the surface structural characteristics of the solids and their dependence on mode of preparation.
