Thedensity(ρ) and speed of sound (u)of the binarymixture (diethylene glycol monoethyl ether (carbitol) + propylene glycol (PG)) have been reported at T= (288.15, 298.15, 308.15 and 318.15) K. The excess molar volume ( ) and isentropic compressibility deviation (Δκs) were calculated using the measured data. The obtained values of ( ) and (Δκs) are negative and positive, respectively, and become more negative and more positive with an increase in carbitol mole fraction. The ρ, u, Vm and κs values of the mixture were correlated by the Jouyban-Acree model with high accuracy. Furthermore, the calculated and Δκs values were correlated well by the Redlich-Kister equation.
