Based on gas–liquid chromatography (GLC) retention data, activity coefficients at infinite dilution of 39 different solutes in the ionic liquid 1-hexyl-1,4-diaza[2.2.2]bicyclooctanium bis(trifluoromethylsulfonyl)imide ([HDABCO][NTf2]) have been determined. Measurements covered a broad range of types of organic solutes including alkanes, alcohols, ketones, benzene derivatives and McReynold’s compounds. Activity coefficients were measured over the temperature range (331.15–363.15) K. The partial molar excess enthalpies of mixing at infinite dilution have been determined based on Gibbs–Helmholtz relationship. Selectivity at infinite dilution values have been also calculated for exemplary separation processes in the systems hexane/benzene and cyclohexane/benzene. The results obtained were analyzed in comparison to literature data for ionic liquids with the same [NTf2]− anion. The obtained results indicate the potential for the application of the investigated ionic liquid in separation problems.
