Infinite dilution partition coefficients (K-factors) of a selection of organic solutes in biphasic 1-n-butyl-3-methylimidazolium dicyanamide–supercritical carbon dioxide (scCO2) system were obtained from retention measurements by open tubular capillary column supercritical fluid chromatography. Further, an improved version of previously developed generalized correlation of the partition coefficients was introduced and tested.
