摘要：
Data on the effect of aqueous-organic solvent composition on molecular complexes formation of 18-crown-6 with glycine, D,L-alanine, and L-phenylalanine have been generalized. The inncrease in ethanol, dimethylsulfoxide, or acetone fraction enhances the complexes stability. Amino acid solvation gives the major impact on the Gibbs free energy of complexes formation. It was demonstrated that stability of 18-crown-6 complexes with amino acids could be predicted basing on changes of the amino acid solvation state.
