摘要:
 以醋酸纤维素为基质膜,以手性金属-有机骨架材料[Zn2Camph2(dabco)]·DMF·H2O作为手性识别剂制备醋酸纤维素混合膜,对D,L-对羟基苯甘氨酸进行了分离研究。该文详细研究了操作压力、操作时间以及D,L-对羟基苯甘氨酸浓度对膜渗析性能的影响。在优选分离条件下,当D,L-对羟基苯甘氨酸浓度为0.3mg/mL时,该膜对D,L-对羟基苯甘氨酸分离的对映体过剩值(e.e.)为42.4%,其对D,L-对羟基苯甘氨酸对映体有一定的拆分效果。
 A enantioselective membrane was prepared by mixed [Zn2Camph2(dabco)]·DMF·H2O and cellulose acetate. The enantioseparation parameters of the mixed membrane for D,L-p-hydroxyphenylglycine was optimized by operating pressure, dialysis time, feed concentration of D,L-p-hydroxyphenylglycine, etc. When the feed concentrateion of D,L-p-hydroxyphenylglycine was 0.3mg/mL, over 42.4% of enantiomeric excess(e.e.) could be obtained by dialysis. The results showed that the MOFs-cellulose acetate mixed membrane can separate the optical isomers of D,L-p-hydroxyphenylglycine.
