ABSTRACT

The densities, q and the speeds of sound, u, for {2-(2-hexyloxyethoxy)ethanol (C6E2) + methanol, +1-propanol, +1-pentanol, and +1- heptanol} have been measured as a function of composition using an Anton-Paar DSA 5000 densimeter at temperatures (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure over the whole concentration range. The q and u values were used to calculate excess molar volumes, VE, and excess molar isentropic compressibility, KE S;m, respectively. Also, thermal expansivity, a, partial molar volume, V i, and partial molar volume of the components at infinite dilution, V 0i , have been calculated. The variation of these properties with composition and temperature of the mixtures are discussed in terms of molecular interactions.
