Abstract: A number of capillary columns with stationary liquid phases based on mono- and dication pyridinium ionic liquids (ILs) were prepared. Their polarity was evaluated using McReynolds system and the selectivity was estimated from intermolecular interactions. The parameters of intermolecular interactions were obtained from retention data using the (Abraham) model of the linear free energy relationship. The dependences of intermolecular interactions on the structure of the cation in the ILs under study were revealed. The results were compared with the data for the traditional phases (HP-5, ZB-WAX). Examples of separation of mixtures of oxygen-containing compounds on the phases under study are given.
