Volumetric behaviour of binary and ternary liquid systems composed of ethanol, isooctane, and toluene at temperatures from (298.15 to 328.15) K. Experimental data and correlation
چکیده انگلیسی

The densities and speeds of sound of (ethanol + isooctane), (ethanol + toluene), and (ethanol + isooctane + toluene) were measured at four temperatures over the range (298.15 to 328.15) K, and the respective values of excess volumes VmE and adiabatic compressibility κS   were calculated. The VmE and κS values for the binary systems were fitted to the Redlich–Kister equation. The respective ternary data together with corresponding binary data were then fitted to the modified Redlich–Kister equation considering various numbers of ternary constants. It was found that even for the systems containing self-associating alcohol, only one ternary parameter is sufficient to describe well the ternary system.


► We measured density and speed of sound at four temperatures within (298.15 to 328.15) K.
► Excess quantities were calculated and fitted to the Redlich–Kister equation.
► The complete ternary data were fitted to the modified Redlich–Kister equation.
► Even for the systems with self-associating alcohol, only one ternary parameter is sufficient.
