| 摘 要： | 以双水相体系为手性识别体系, 研究了异丙醇/盐和TritonX-114温度双水相体系中扁桃酸的分配行为. 对于醇/盐体系, 扁桃酸均倾向于分配在醇相中, 不适合作为手性识别系统; 而对于TritonX-114温度双水相体系, 扁桃酸富集于水相, 适合作为手性识别系统. 以L-酒石酸正戊酯和β-环糊精作为手性识别剂, 对TritonX-114/L-酒石酸正戊酯、TritonX-114/L-酒石酸正戊酯/茶皂素和TritonX-114/β-环糊精3个识别体系的研究发现, TritonX-114/L-酒石酸正戊酯/茶皂素和TritonX-114/β-环糊精体系中, 手性识别效果明显, 最佳分离体系为: 茶皂素含量0.51 mmol, L-酒石酸正戊酯含量1.4 mmol, 温度55 ℃, 最大分离因子1.29.

| Abstract: | The partitioning behavior of mandelic acid was studied on the isopropyl alcohol/salt and TritonX-114 temperature induced system.The results show that the mandelic acid tends to exist in the isopropyl alcohol phase of the isopropyl alcohol/salt system,and in the water phase of the TritonX-114 temperature induced system,so the TritonX-114 temperature induced system was used as chiral recognition system.The chiral recognition of mandelic acid was investigated in the TritonX-114/n-amyl-L-tartrate/teasaponin and... |
