The silica gels treated with alcohols in long chain hydrocarbons by the reflux method have been investigated from the standpoints of the numbers of surface group, IR spectra, argon surface area and the preferential dispersion into mixed media like oil and water. The results revealed the similar trend in those properties of surface group to those for the surface-treated silica gels through the autoclave method reported previously. The surface group of silica gels treated with cetyl alcohol has been recognized to take the position parallel to the silica gel surface for a small amount of surface group, but changes to the vertical position when the number of surface group increases.
