摘要：

Ultrasonic speeds were measured in 2-(2-ethoxyethoxy)ethanol + water and 2-(2-butoxy ethoxy)ethanol + water systems across their entire composition ranges, at the temperature 298.15 K, using a sing-around technique, at a frequency of 1.8 MHz. Measurements were also made of the densities of the two systems. From these measurements, values of the molar and excess molar volumes were obtained together with the values of - (partial derivative V(m)/partial derivative p)S,m and the corresponding excess quantities. The various excess quantities were analysed using a segmented-composition model.
