and R. K. Bhardwaj
The excess molar volume and ultrasonic speed have been measured in dipropylene glycol monomethyl ether + butylamine, dibutylamine, and tributylamine across the entire composition range, at the temperature 298.15 K and atmospheric pressure. The ultrasonic speed values have been combined with those of the excess molar volumes converted to densities to give estimates of the product KS,m of the molar volumes and isentropic compressibility κS and the excess quantity KS,mE. The excess volumes are negative over the entire range of composition for all mixtures with the exception of tributylamine. The KS,mE values are negative for all mixtures. The deviation of the speeds of sound uD from their ideal values uid in an ideal mixture were also calculated for all measured mole fractions. Graphs of VmE, u, uD, and KS,mE against composition are presented as a basis for a qualitative discussion of the results.
