"From extraction experiments and gama-activity measurements, the exchange extraction constants corresponding to the general equilibrium C+(aq) + 1?Na+(nb) ? 1?C+ (nb) + Na+(aq) taking place in the two-phase water-nitrobenzene system (C+ = protonated alfa-amino acid methyl ester, 1 = benzo-18-crown-6; aq = aqueous phase, nb = nitrobenzene phase) were evaluated. Furthermore, the stability constants of the 1?C+ complex species in nitrobenzene saturated with water were calculated; they were found to increase in the following cation order: protonated L-tryptophan methyl ester { protonated L-phenylalanine methyl ester { protonated L-leucine methyl ester, protonated L-methionine methyl ester { protonated L-valine methyl ester." . . . .
