Activity coefficients at infinite dilution of pentane, hexane, heptane, octane, nonane, cyclohexane, methylcyclohexane, 2,2,4-trimethylpentane, cyclohexene, styrene, benzene, toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene in 1-decyl-3-methylimidazolium tetrafluoroborate have been determined using gas−liquid chromatography over a temperature range (303.15 to 363.15) K with the ionic liquid as stationary phase. The partial molar excess enthalpies were also for solutes from dependence experimental activity values.
