Surface-modified chromatographic separation material |
摘要 |
A method is provided for modifying a porous chromatographic material such as silica, alumina, thoria, titania or magnesia, which involves the steps of halogenating the surface hydroxyl groups of such material, and reacting the halogenated surface with a suitable alkylation reagent. The method gives a direct surface-to-carbon linkage in a high-yield reaction.
