Description 735-745
The densities, ρ, and the speeds of sound, u, for binary liquid mixtures containing propylene glycol monopropyl ether
(PGMPE) and n- butylamine (BA), dibutylamine (DBA) or tributylamine (TBA) have been measured as a function of
composition using a vibrating tube densimeter and sound analyzer Anton-Paar model DSA-5000 at temperatures 288.15,
298.15 and 308.15 K and atmospheric pressure. From these data excess molar volumes, Vm
E , the thermal expansion
coefficient, αE, and deviations in isentropic compressibility, Δκs, have been calculated.. The Vm
E values are negative over the
whole mole fraction range for the systems propylene glycol monopropyl ether + n-butylamine, and dibutylamine, and
positive for the system propylene glycol monopropyl ether + tributylamine. whereas the Δκs values are negative over the
entire range of composition for all mixtures with the exception of tributylamine. Also, in the present study, thermophysical
parameters such as apparent molar volume ,vФ,i, and apparent molar isentropic compressibility, K φ,i are studied for the
PGMPE with BA, DBA or TBA. The results reveal the dominance of ether – BA or DBA as compared to ether –TBA
interactions which are found to increase with elevation of temperature but decrease with increasing the chain length of
alkylamine. Further, the deviation of the speeds of sound uD from their ideal values uid in an ideal mixture have been
calculated for all measured values of mole fraction x1. Sign and magnitude of Vm
E, Δκs and uD with respect to the
composition and temperature have been used to analyze the mixing behavior of the components.
