Abstract

The heat effects of solution of 18-crown-6 ether were determined calorimetrically over a wide range of water-acetone solvent compositions (298.15 K). The influence of the composition of water-acetone solvents on the enthalpies of complex formation between 18-crown-6 and glycine and solvation of chemical equilibrium participants was studied. It was shown that the factor determining changes in the enthalpy of the reaction was changes in the solvation state of the crown ether.
