Resumo
The influence of the composition of the methanol—acetonitrile (MeOH—AN) solvent on the solvation of 18-crown-6 ether (18C6) has been studied. Increasing fraction of AN in the binary solvent stabilizes the 18C6 solvation complex by increasing the exothermicity of 18C6 solvation. Analysis of the solvation contributions of the reagents to the enthalpies of complex formation of silver(I) ion with 18C6 in MeOH—AN mixtures has been performed to establish that the decrease in the exothermicity of complex formation in going from MeOH to AN is mostly associated with the solvation contribution of Ag(I).
