ABSTRACT

Densities, F, and speeds of sound, u, of systems formed by 1-butanol (1-BuOH), 1-pentanol (1-PeOH), or 1-HxOH (1-hexanol) and dibutylether (DBE) have been measured at (293.15, 298.15, and 303.15) K and atmospheric pressure using a vibrating-tube densimeter and sound analyzer Anton Paar model DSA-5000. The F and u values were used to calculate excess molar volumes, VE, and deviations from the ideal behavior of the thermal expansion coefficient, RP, and of the isentropic compressibilities, eT. The VE variation with the chain length of the 1-alkanol shows the existence of structural effects for systems including longer 1-alkanols.
