ABSTRACT
The densities and speeds of sound of (methyl tert-butyl ether {MTBE} + toluene + isooctane) were measured at four temperatures over the range (298.15 to 328.15) K and the respective values of excess volumes VE and adiabatic compressibility kappa_S were calculated. The VE and kappa_S values for the ternary and corresponding binaries were fitted to the Redlich Kister equation considering various numbers of ternary constants. The necessary number of ternary constants needed to describe the system is discussed.
