The density (ρ) and speed of sound (u) of the binary mixture (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 and become more negative and more positive, respectively. 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 by the Redlich-Kister equation.
