摘要
A process for separating organic compounds from a mixture by reverse- phase displacement chromatography, including providing a hydrophobic stationary phase; applying to the hydrophobic stationary phase a mixture comprising organic compounds to be separated; displacing the organic compounds from the hydrophobic stationary phase by applying thereto an aqueous composition comprising a non-surface active hydrophobic cationic displacer molecule and about 10 wt% or less of an organic solvent; and collecting a plurality of fractions eluted from the hydrophobic stationary phase containing the separated organic compounds; in which the non-surface active hydrophobic cationic displacer molecule comprises a hydrophobic cation and a counterion, CI, having the general formula A or B, as defined in the disclosure:
