摘　　要：把钛胶与乙烯基三乙氧基硅烷在甲苯中回流 ,得到乙烯基硅烷键合的钛胶 ,然后再与乙基苯乙烯和二乙烯基苯聚合 ,制备了乙基苯乙烯 二乙烯基苯包覆的钛胶反相高效液相色谱固定相 ,简称为ES DVB TiO2 。从固定相的疏水选择性、绝对流动相灵敏度以及化学稳定性几方面对其进行了评价。在实际分离分析中 。Ethylstyrene divinylbenzene coated TiO 2 (ES DVB TiO 2) 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 TiO 2 These examples showed that ES DVB TiO 2 synthesized in our laboratory was a good reversed phase stationary phase
