- 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
