| Abstract | Speeds of sound have been measured in dipropylene glycol monobutyl ether + methanol, 1-propanol, 1-pentanol, 1-heptanol, across the entire composition range, at the temperature 298.15 K and atmospheric pressure. The speed of sound values were combined with excess molar volume to obtain values for the product K-s,K-m of the molar volume and the isentropic compressibility kappa(s), and the corresponding quantities K-s,(E)(m) were also calculated. The K-S(E),m values are negative for all mixtures. The deviation of the speeds of sound u(D) from their values u(id) in ideal mixtures were obtained for all measured mole fractions. These values are compared with mixing function deltau. The behaviour of u, deltau, u(D), and K-S(E),m as a function of composition and number of carbon atoms in the alcohol molecule is discussed. |
