(4-环戊二烯基苯甲酸-铁-甲苯)六氟磷酸盐 键合硅胶固定相的制备及色谱性能
Preparation and chromatographic performance of a silica-bonded( 4-cyclopentadienyl benzoic acid-iron-toluene) hexafluorophosphoric acid stationary phase
摘要
Abstract
Based on the unique molecular structure of ferrocene and its potential as a new liq-uid chromatography separation medium,a new silica-bonded(4-cyclopentadienyl benzoic acid-iron-toluene)hexafluorophosphoric acid stationary phase was prepared. The structure of this new material was characterized by infrared spectroscopy,elemental analysis,thermogravimet-ric analysis et al. The chromatographic performance and retention mechanism of this new sta-tionary phase were evaluated using different solute probes,including polycyclic aromatic hydro-carbons( PAHs ),positional isomers of naphthylamine,positional isomers of nitro-aniline, nitroimidazoles,organic phosphorus et al. It could provide various action sites for different sol-utes in normal-phase chromatography such as π electron transfer,π-π electron interactions, dipole-dipole interactions,and electrostatic interactions with the substrates. And the possible separation mechanisms are discussed.关键词
