Further, the chiral discrimination model via the formation of ionic diastereomers, as proposed by Bhushan and Parshad [8] in Scheme 13.1, was viewed by Kowalska and coworkers [11] in terms of the energy difference for ion-pair formation (i.e., in the formation of the two diastereomeric salts). Ibuprofen is a carboxylic acid and, therefore, apt to dissociate (and form an organic anion) and the separation of the two enantiomers of ibuprofen can be achieved only because the thermodynamic equilibrium constants (K) for the ion-pair formation process for the two enantiomers (Ki and K2, respectively) have different numerical values. From the theory of adsorption liquid chromatography, it is well known [15] that the thermodynamic equilibrium constant of adsorption, K, can be defined as follows ...
