β 环糊精由于其特殊的分子结构 ,对某些物质具有包结作用 ,并形成较稳定的复合物 ,极化能力大大增强 ,在色谱中具有更大的保留值 ,气相色谱固定相分离混合物过程中 ,β 环糊精包结物较β 环糊精具有更强的分离能力。分别对β 环糊精及其包结了某些物质后的 β 环糊精作气相色谱固定相 ,对一系列低佛点有机化合物的分离和保留行为进行研究 ,比较了β 环糊精包结前后的不同的分离效果 ,并初步探讨了有关的形成机理和分离机制
Due to its special molecular structure, β-cyclodextrin has the effect of entrapment to some substances and forms a more stable complex, the polarization ability is greatly enhanced and has a larger retention value in the chromatogram. The gas chromatographic stationary phase separates the mixture Β cyclodextrin inclusion has stronger separation ability than β-cyclodextrin. The β-cyclodextrin and β-cyclodextrin-coated β-cyclodextrins were respectively used as the stationary phase of the gas chromatography to study the separation and retention behavior of a series of low-lying point organic compounds. Of the different separation effects, and preliminary discussion of the formation mechanism and separation mechanism
