摘要：

Chiral ionic liquid L-alanine tert butyl ester bis(trifluoromethane) sulfonimide(L-AlaC(4)NTf(2)) was synthesized and mixed with OV-1701 at different ratios, and used as new stationary phase in capillary GC. The results show that the thermal stability of ionic liquid capillary column can reach to 175 degrees C, the average value of McReynolds constants is 665, and its column efficiency is 1095 plate/m when the retention factor is 1.02. Their separation selectivities are toward alkanes, alcohols, ketones, aromatic compounds, positional isomers and some chiral compounds.
