摘要:
壳聚糖(CTS)作为天然高分子材料,改性后具有一定的分子识别和手性识别功能.采用香草醛(3,4-二氧亚甲基-苯甲醛)接枝到壳聚糖的链上,然后通过偶联剂γ-缩水甘油醚氧丙基三甲氧基硅烷将其与硅胶键合制备出新型液相色谱固定相.香草醛接枝壳聚糖(VCTS)的制备,计算了接枝率,确定了分子量.然后将香草醛接枝壳聚糖(VCTS)作为反应的原料,制备键合硅胶固定相(VCTS-KH560-Si),并用傅立叶变换红外光谱、热分析和质量分析法等手段进行表征,证明键合产物性质稳定.研究了其对手性物质的分离性能,并讨论了分离效
Abstract:
As a natural polymer material, chitosan (CTS) has certain molecular recognition and chiral recognition functions after modification. Vanillin (3,4-dioxanemethylene-benzaldehyde) was grafted onto the chain of chitosan, and then a novel liquid chromatography stationary phase was prepared by bonding it with silica gel by coupling agent γ-glycidyl etheroxypropyltrimethoxysilane. The grafting rate of vanillin grafted chitosan (VCTS) was prepared, and the molecular weight was determined. Vanillin-grafted chitosan (VCTS) was then used as the raw material for the reaction to prepare the bonded silica gel stationary phase (VCTS-KH560-Si), and characterized by Fourier transform infrared spectroscopy, thermal analysis and mass analysis to prove that the bonding products were stable. The separation properties of chiral substances were studied, and the separation effects were discussed
