Abstract: The surfaces of porous silicon dioxide chromatographic adsorption means are altered by chemical reaction of silanol groups with primary or secondary aliphatic or araliphatic amines having at least two carbon atoms and containing no functional groups as substituents that might competitively react with respect to the amino groups. The amines are preferably substituted in the omega-position with at least one noncompetitive functional group. Such terminal functional groups may subsequently be reacted with compounds which further alter the surface to provide optimal surface groups in the stationary phase for given separation and chromatographic problems.

Abstract: Stationary phases for chromatographic ion exchange or catalysis produced by esterification of solid substances having acidic OH groups at the surface as Components I with organic compounds as Components II. The specific surface area of Components I is above 100 cm2/g and Components II each have at least one hetero atom in their molecules, disregarding the oxygen connected to a carbon atom in the molecule for esterification with the acid OH group in Component I. By hetero-atoms is meant an atom other than carbon and hydrogen.
