A typical application of an RTILCO2 system would involve a reaction in the RTIL environment, and a subsequent extraction of the reactants and products from the RTIL with supercritical CO2. For both fundamental understanding and process utilisation of such a procedure, high-pressure partition coefficients are necessary of the substances concerned between both phases in the RTILCO2 system. Supercritical fluid chromatography (SFC) with the RTIL as the stationary liquid phase and CO2 as the mobile-phase fluid presents a convenient and inexpensive route to the partition coefficients, at least in low-volatility solutes. In this contribution, we report the results of a feasibility study in naphthalene1-butyl-3-methylimidazolium hexafluorophosphateCO2 system.
