摘要：

以聚醚砜膜作为基膜，以万古霉素、1,6-己二异腈酸酯作为单体，利用界面聚合的方法制备了万古霉素-己二异腈酸酯聚醚砜手性高分子复合膜，使用自制的膜色谱装置结合高效液相色谱仪，对手性物质D,L-苯甘氨酸进行了手性膜色谱分离研究。该文详细研究了流速、流动相、进样量、膜的层数、膜的尺寸对拆分效果的影响。在优选分离条件下，该手性膜色谱法对D,L-苯甘氨酸拆分的分离因子(α)和分离度(Rs )分别为5.66、0.66，该方法的最大优点是在水环境下能对手性化合物进行分离制备，这在色谱的手性分离中是少见的。

Using vancomycin and 1,6-diisocyanatehexane as monomers, an enantioselective composite membrane was prepared by interfacial polymerization on a polyethersulfone support. After the composite membrane was mounted in a home-made device of membrane chromatography for high performance liquid chromatography, the enantioseparation of D,L-phenylglycine was carried outed by the chiral membrane chromatography. By optimizing the injection volume, the flow rate, the constituent of mobile phase, the size of the membrane, the layer numbers of the membrane, over 5.66 of separation factor (α) and 0.66 of resolution (Rs ) could be obtained, respectively. The advantage of the method is the ability to separate and prepare chiral compounds in an aqueous environment, which is rare in chromatographic chiral separation.
