ABSTRACT:
Functionalized silicas which can be used as core supports for a broad variety of chiral stationary phases may be conceptually represented as T--O--Si--U. T represents a refractory inorganic oxide, and T--O--Si arises from reaction of an organosilane with the surface hydroxyl groups of the refractory inorganic oxide. U represents a polyamine, related to poly(ethyleneamines), tris(2-aminoethyl) amine, or alkyleneoxyamines of glycerine.
