摘　　要：以胆甾型苯并－１５－冠－５涂渍于硅烷化１０２白色担体作为一种新的ＧＣ固定相，柱温在１２５℃以下（固体固定相）、１２５℃以上（液体固定相）及由１８２℃降至１２５℃以上（冠醚液晶固定相）三种情况下，对几种取代苯位置异构体的分离效果进行了比较研究，并探讨了分离机理。Separation of positional isomers of some substituted benzenes with CH-B-15-C-5 as GC stationary phase was studied in this paper. The chromatographic characteristics of CH-B-15-C-5 were also studied. The results of separation of positional isomers were discussed.
