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（ＧＳＣ）、普通气液色谱（ＧＬＣ）和冠醚液晶气液色谱（ＣＬ－ＧＬＣ）多种性能的固定相．用该固定相在不同条件下，对脂肪烃、脂肪醇、羧酸乙酯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，均获得对称性良好的色谱峰．还研究了该固定相的极性、选择性和稳定性等色谱性能，初步探讨了分离机理
4’-Cholestinyloxycarbonyl-benzo-15-crown-5 (CH-B-15-C-5) has different phase states in different temperature ranges and has different physical properties due to different treatment methods in the same temperature range It has been used as a stationary phase for a wide range of properties including gas-solid chromatography (GSC), common gas-liquid chromatography (GLC) and crown ether liquid-gas chromatography (CL-GLC) Using this stationary phase, GSC, GLC and CL-GLC separation of aliphatic hydrocarbons, fatty alcohols, ethyl esters of carboxylic acids and various organic compounds were carried out under different conditions and found to have strong separation capacity for these substances Get good symmetry peaks. The chromatographic properties such as polarity, selectivity and stability of the stationary phase were also studied. The mechanism of separation
