摘    要:4‘-胆甾烯氧羰基苯并-15-冠-5(CH-B-15-C-5)在不同温度范围内其相态不同,在同一温度范围内因处理方式不同而物性亦相去甚远,用其作成了兼具气固色谱,普通气液色谱和冠醚液晶气液色谱多种性能的固定相。用该固定相在不同条件下,对脂肪烃,脂肪酸,羧酸乙以及多种有机混合物等进行了GSC,GLC和CL-GLC分离,发现它对这些物质有较强的分离能力,均获得对称良好的色谱峰。

关 键 词:胆甾 液晶 冠醚 气相色谱 固定相

Abstract:The chromatographic characteristics,such as,the chemical stability,thermal stability,polarity,selectivity and the allowable operating temperature range,of CH B 15 C 5 as stationary phase for GC were studied in this paper.The separations of C 1-C 6 alcohols,ethyl asters of C 1-C 8 carboxylic acid,C 5-C 12 n alkanes and the other organic compounds mixtures were carried on the column packed with CH B 15 C 5.The results of separation were satisfactory.A possible retention mechanism is proposed to explain retention behaviours of the substances.
Keywords:? Cholestenoxycarbonyl benzo 15 crown 5  liquid crystalline crown ether  gas chromatography  stationary phase
