✦ Synopsis

Densities and ultrasonic speeds of binary mixtures of water with ethylene glycol monopropyl ether have been measured at 298.15 K over the entire composition range. Estimates of the isentropic molar quantity, Ks, equal to -(~V/Op)s, and of its excess counterpart, Ks s, were obtained from the density values, in combination with those of the ultrasonic speed. Our results have been compared with those reported earlier for 2-propanol +, and ethylene glycol monoisopropyl ether + water systems, and with literature data relative to the l-propanol + water system. The various excess molar quantities have been analyzed using segmented-composition models, including a version onto which a mass action component has been grafted.
