Volumetric behaviour of the ternary liquid system composed of methyl tert-butyl ether, toluene, and isooctane at temperatures from (298.15 to 328.15) K: Experimental data and correlation

Moravkova L, Wagner Z, Sedlakova Z, Linek J

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 V-m(E) adiabatic compressibility kappa(S) were calculated. The V-m(E) 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. (c) 2010 Elsevier Ltd. All rights reserved.
