ABSTRACT

The densities, ?, and speeds of sound, u, have been measured as a function of composition for binary liquid mixtures of dipropylene glycol monopropyl ether (DPGMPE) with n-butylamine (BA), dibutylamine (DBA), and tributylamine (TBA) at (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure using an Anton Paar DSA-5000 instrument. The ? and u values were used to calculate excess molar volumes, V E, deviations from the ideal behavior of the thermal expansion coefficient, a E, and the isentropic compressibilities, ?? S . Moreover, the apparent molar volume , and apparent molar compressibility , of the components have been calculated at infinite dilution. The Jouyban Acree model is used to correlate the experimental values of density and ultrasonic speed at different temperatures.
