摘    要:制备并表征了涂敷纤维素-三(3,5-二甲基苯基氨基甲酸醋)-ZrO2手性固定相。以正己烷/异丙醇为流动相,研究了正相色谱条件下手性固定相对几类光学异构体的手性拆分能力。实验结果表明:氧化锆载体表面的碱性性质对光学对映体的手性拆分有很大影响;在常用流动相条件下,酸性对映体被完全滞留;纤维素-三(3,5-二甲基苯基氨基甲酸醋)-ZrO2手性固定相对于中性及碱性对映异构体的分离呈现出较好的手性拆分能力。

关 键 词:纤维素-三(3,5-二甲基苯基氨基甲酸酯)-氧化锆  手性固定相  制备  色谱评价  高效液相色谱  生性分离  填料

Abstract:The paper describes a procedure for preparing cellulose-tris(3,5-dimethylphenylcarbamate) coated zirconia (CDMPC-coated ZrO 2). Some neutral, basic and acidic enantiomers were enantioseparated under normal-phase conditions by high-performance liquid chromatography. Experimental results show that surface basic property of zirconia has profound influences on retention, selectivity and resolution of different racematic mixtures. Good enantiomeric resolutions for neutral and basic analytes were achieved, while acidic enantiomer did not elute from the column unless an acidic additive was presented in mobile phase.
Keywords:Zirconia  cellulose-tris(3  5-dimethylphenylcarbamate) coated zirconia    chiral stationary phase  enantiose-paration  high performance liquid chromatography
