[Synthesis and evaluation of ethylstyrene-divinylbenzene-coated titania for high performance liquid chromatography].
Ethylstyrene-divinylbenzene-coated TiO2 (ES-DVB-TiO2) was synthesized by at first bonding of vinyltriethoxysilane with hydroxyl group on titania and secondly by addition polymerization of vinyltriethoxysilane and ethylstyrene-divinylbenzene. The hydrophobic selectivity, absolute mobile phase sensitivity, and stability of the stationary phase were evaluated. Finally, several kinds of practical separations were tested on ES-DVB-TiO2. These examples showed that ES-DVB-TiO2 synthesized in our laboratory was a good reversed-phase stationary phase.
