✦ Synopsis

The speeds of sound in {xH(CH2)n O(CH2)2O(CH2)2OH + (1-x)H2O} for n=1, 2, and 4 have been measured over the whole range of x at the temperature T=298.15 K. The molar isentropic compressibilities KS, m of these solutions were estimated from the products of the molar volume and the isentropic compressibility kS , and the excess values K E S, m were also calculated. The behaviour of the K E S, m curves for the series of mixtures is similar to that found previously for their excess molar volumes. Also, the deviations of the speeds of sound u D has been defined and calculated for all measured values of x. These values were compared with the mixing function du calculated in the literature. The behaviour of u D , du, and K E S, m with composition and the number of carbon atoms in the aliphatic chain of the alkoxyethanol is discussed.
