环糊精类固定相分离二甲萘位置异构体

Separation of Dimethylnaphthalenes on β-Cyclodextrins

研究了 9种特殊固定相GC毛细管柱对 10种二甲萘异构体的分离特性 ,结果表明 :七 (2 ,6 二 O 戊基 3 O 丁酰基 ) β 环糊精、七 (2 ,6 二 O 戊基 3 O 庚酰基 ) β 环糊精、PLC 1能分离除了 2 ,6 二甲萘和 2 ,7

The separation behaviors of all the ten positional isomers of dimethylnaphthalene in nine gas chromatographic stationary phases columns were studied. The results indicated (DMN) that all the positional isomers of dimethylnaphthalene except for 2,6-DMN and 2,7-DMN can be separated very well in haptakis(2,6-di-O-pentyl-3-O-butyryl)-β-cyclodextrin (β-CD), haptakis(2,6-di-O-pentyl-3-O-heptanoyl)-β-CD and polymer liquid crystal-1 stationary phases columns.
