摘要：

Enthalpies of dissolution in water for 12-crown-4, 15-crown-5, and 18-crown-6 were determined calorimetrically in the temperature range 288.15 to 308.15 K. Heat capacities for the three pure compounds were determined at 298.15 K, using a drop-calorimetric technique, and the enthalpy of sublimation of 18-crown-6 was determined calorimetrically at 298.15 K. Values for enthalpies of solvation and for partial molar heat capacities at 298.15 K are calculated for infinitely dilute solutions. Discussion of the results is based on an empirical additivity relation. © 1990.
