Partial Molar Volumes and Partial Molar Isentropic Compressions of 15-Crown-5 and 18-Crown-6 Ethers at Infinite Dilution in Water at Temperatures T = (278 to 343) K and Atmospheric Pressure
Density and speed of sound data for dilute aqueous solutions of two crown ethers, 15-crown-5 and 18-crown-6, were measured using the Anton Paar DSA 5000 vibrating-tube densimeter and sound analyzer in the temperature range from (278.15 to 343.15) K and at atmospheric pressure. Standard molar volumes and standard molar isentropic compressions were evaluated from the measured data. Present data were combined with those obtained previously for lower cyclic ethers, and the predictions of standard molar volumes and standard molar isentropic compressions based on a group contribution approach were tested and analyzed.
