Abstract

Abstract: In the separations of ethylbenzene/benzene, o-xylene/benzene, styrene/benzene, styrene/toluene and styrene/ethylbenzene on the mixed stationary phases composed of perpentylated β-CD and AgNO₃, perpentylated β-CD and TlNO₃, Benton-34 and AgNO₃ in GC, the positive synergistic effects or negative synergistic effects were discoveried. This phenomenon was investigated carefully. The effects of separation temperature, and how the stationary phases to be mixed were accomplished.

Key words: Synergistic effects, Mixed stationary phase, GC
