本工作的目的是研究壳聚糖衍生物的溶胀性对手性固定相对映体拆分和分离性能恢复的影响。因此,我们合成了6种壳聚糖双(苯氨基甲酸酯)-(正辛基尿素)S,并将其包覆在大孔3-氨基丙基硅胶上,得到了新的壳聚糖聚合物。大多数CSP对被测试的手性化合物表现出很强的拆分能力。考察了壳聚糖双(苯氨基甲酸酯)-(正辛基尿素)S在乙酸乙酯、丙酮和四氢呋喃中的溶胀性能。在壳聚糖衍生物中,壳聚糖双(3,5-二氯苯基氨基甲酸酯)-(正辛基尿素)聚合物在乙酸乙酯和四氢呋喃中表现出最大的溶胀容量。聚合物基CSPs可与纯乙酸乙酯和含70%THF的正相一起使用,但会被纯THF破坏。另一方面,受损的CSP在放置一段时间后,其分离性能可以恢复。这些观察结果对基于多糖衍生物的CSPs的开发和应用具有重要意义。
The goal of the present work was to study the influence of the swelling of chitosan derivatives on the enantioseparation and the separation performance recovery of chiral stationary phases (CSPs) based on these derivatives. Therefore, six chitosan bis(phenylcarbamate)-(n-octyl urea)s were synthesized, which were coated on macroporous 3-aminopropyl silica gel affording new CSPs. Most of the CSPs demonstrated strong enantioseparation capability for the tested chiral compounds. The swelling capacity of the chitosan bis(phenylcarbamate)-(n-octyl urea)s in ethyl acetate, acetone and tetrahydrofuran (THF) was evaluated. Among the chitosan derivatives, the chitosan bis(3,5-dichlorophenylcarbamate)-(n-octyl urea) polymer showed the highest swelling capacity in ethyl acetate and THF. The polymer-based CSPs could be utilized with pure ethyl acetate and a normal phase containing 70% THF, but was damaged by pure THF. On the other hand, the separation performance of the damaged CSP could be recovered after it was allowed to stand for a period of time. The observations are important for the development and application of polysaccharide derivative-based CSPs.
