The solution and solvation enthalpies at infinite dilution of 15-crown-5 in different organic solvents and water were measured. The limiting partial molar volumes of the crown ether in a series of solvents studied were determined using experimental density data. On the basis of the scaled particle theory the satisfactory multiparameter correlation of the quantities measured 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.
