Complexation of some protonated alpha-amino acid methyl esters with benzo-18-crown-6 in nitrobenzene saturated with water
Original language description
From extraction experiments and gamma-activity measurements, the exchange extraction constants corresponding to the general equilibrium C+(aq) +1 center dot Na+(nb)double left right arrow 1 center dot C+ (nb)+Na+ (aq) taking place in the two-phase water-nitrobenzene system (C+ = protonated alpha-amino acid methyl ester, 1=benzo-18-crown-6; aq=aqueous phase, nb = nitrobenzene phase) were evaluated. Furthermore, the stability constants of the 1 center dot C+ complex species in nitrobenzene saturated withwater 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.
