Chromatographic studies on the inclusion of isomeric dimethylnaphthalenes by β- and γ-cyclodextrin
Reversed-phase high performance liquid chromatography and gas-liquid chromatography have been applied to studies on the complexation of cyclodextrins with isomeric dimethylnaphthalenes. Both β and γ-cyclodextr...

Retention behavior of the inclusion complexes of some polycyclic aromatic hydrocarbons with β-cyclodextrin
The retention behaviour of a group of polycyclic aromatic hydrocarbons having nearly equal ionization potentials but different molecular polarizability values was investigated by reversed-phase HPLC and gas ch...

Structure-retention studies on the inclusion complex formation of some polycyclic aromatic hydrocarbons with β-cyclodextrin
The retention behaviour of a group of polycyclic aromatic hydrocarbons having nearly equal ionization potentials but different molecular polarizability values was investigated using reversed-phase HPLC. Methan...

Application of a gas-liquid chromatography system with α-cyclodextrin for monitoring the stereochemical course of β-pinene hydrogenation
Complete separation of a mixture containing two enantiomers of β-pinene and four stereoisomers of pinane was achieved by gas chromatography using α-cyclodextrin dissolved in formamide as the stationary phase. ...

Gas-liquid chromatography system with α-cyclodextrin as an analytical tool for the studies of stereoselective hydrogenation of α-pinene
α-Cyclodextrin dissolved in formamide solution was applied as the stationary phase in gas-liquid chromatography for the enantio- and diastereoselective separation of α-pinene and pinanes. It was found that the...

The resolution of some chiral compounds in reversed-phase high-performance liquid chromatography by means of β-cyclodextrin inclusion complexes
β-Cyclodextrin is applied as the chiral component of the mobile phase in a systematic study of the resolution —into enantiomers — of mandelic acid and its derivatives by reversed-phase liquid chromatography. I...
