英文摘要A phosphonium-based ionic liquid IL (tetra-butyl phosphonium methanesulfonate), which possessed high thermal stability and large viscosity, was systematically investigated as a stationary phase for gas chromatography. The IL column was prepared by the static coating method and the chromatographic properties, polarity and retention character of the column were studied. The column efficiency was tested using tetradecane at 120 degrees C. The column provided an efficiency of 1381 plates/m and an average polarity of 559.6, which was comparable to the polarity of the commercial PEG2OM and FFAP. Experimental results showed that the IL column demonstrated strong interaction with the molecules with strong proton donor groups. Both of the retention factor and the selectivity for the meta and para isomers of many aromatic compounds were better on the IL column than those on the PEG20M. In addition, symmetrical peak shapes and unique separation selectivities were obtained when the IL column was used to separate the mixtures of a series of alkanes, polycyclic aromatic hydrocarbons, chlorinated benzenes, alcohols etc.
