title: Gas chromatographic characteristics and application studies of the stationary phase of CH-B-15-C-5.
abstract: In this paper, separations of organic compounds, such as, n-alkanes, alcohols, ethyl asters of C(1)-C(8) carboxylic acid, halogen derivatives, position-isomers of the replacement aromatic hydrocarbon, optical isomers of ethyl lactate and isoamyl alcohol, etc. were studied using 4'-cholestenoxycarbonyl-benzo-15-crown-5 liquid crystal crown ether (CH-B-15-C-5) as stationary phase in gas-solid chromatography (GSC), general gas-liquid chromatography (GLC) and crown ether liquid crystal gas-liquid chromatography (CL-GLC). Also, the chromatographic characteristics, such as the chemical stability, thermal stability, selectivity, polarity and operating temperature range, of the CH-B-15-C-5 as stationary phase for GSC, GLC and CL-GLC systems were studied. The results showed that the polarity of this chromatographic column is mean-weak; the chemical and thermal stabilities and the selectivity are good and the operating temperature range is wide. The results of separations of organic compounds are satisfactory.
