Determination of the reactive surface area of silica

Short Communications

Summary

The surface area available for reaction in silylation reactions has been determined by reaction of the silica with a radioactively labelled alkyldimethylchlorosilane followed by liquid scintillation counting of either a solid or a dissolved silica sample. The results are compared with values obtained by nitrogen adsorption and the pore size distributions of the products before and after reaction.
