Correlation of enthalpic and volume characteristics of 15-crown-5 in solution with molecular parameters and physical properties of solvents

The solution and solvation enthalpies at infinite dilution of 15-crown-5 in different organic solvents and water were measured. The limiting partial m olar volumes of the crown ether in a series of solvents studied were determ ined using experimental density data. On the basis of the scaled particle t heory the satisfactory multiparameter correlation of the quantities measure d with properties of solvents was obtained. The known equations as modified by the introduction of more accurate radial distribution function g(12)(r) were used. (C) 1999 Elsevier Science B.V. All rights reserved.
