The obtained chiral stationary phases ( CSPs) were evaluated by high performance liquid chromatographic (HPLC) resolution of 9 racemates (3-butyl-phthalide, ketoprofen, trans-stilbene oxide, benzoin, benzoin analogue, Tr?ger' s base, warfarin, 4,4'-dimethoxy-5,6,5',6'-dimethylenedioxy-biphenyl-2,2'-dicarboxylate and 4,4'-dimethoxy-5,6,5',6'-dimethylenedioxy-biphenyl-2-methylcarboxylate-2'-ethylcarboxylate). For regio-nonselective procedure, increasing the content of vinyl group on CTMB would lead to higher immobilization efficiency and enantio-selectivity. CSPs prepared by regio-selective procedure possessed slightly higher enantioselectivities than those prepared by regio-nonselective procedure, while the latter showed some advantages for rapid and facile preparation. CSPs prepared with silica gel II (Fuji, 5 microm, 30 nm, ca. 150 m2/g) showed higher enantioselectivities than those prepared with silica gel I (Kromasil, 5 microm, 20 nm, ca. 240 m2/g). The prepared CSPs could keep stable under different eluents, even with 40% of tetrahydrofuran (THF) in mobile phases. %K cellulose tris (4-methylbenzoate) derivatives %K chemical bonding %K chiral stationary phase %K chiral separation
