通过芘基丁酸键合硅胶固定相对含π电子物质的分离研究,考察了该固定相的色谱性能.结果表明,该固定相不仅具有疏水作用和电荷转移性能,还具有很强的平面识别能力,可很好地分离烷基苯、稠环芳烃及取代硝基苯等各种含π电子物质,且在pH 3.5~7.0时化学稳定性能良好,硅醇基效应得到了很好的抑制,可有效地用于碱性化合物的分离分析. The study on the separation of π-containing compounds from pyrene-bonded butyric acid-bonded silica gel stationary phases showed that the stationary phases not only had hydrophobic and charge-transfer properties, but also had strong ability of plane recognition , Which can separate various kinds of π-electron-containing substances such as alkylbenzenes, condensed-ring aromatic hydrocarbons and substituted nitrobenzene well, and has good chemical stability at pH 3.5-7.0 and good silanol group effect. Effectively used for the separation and analysis of basic compounds.
