ABSTRACT

The densities and speeds of sound of (toluene + isooctane), (MTBE + toluene), and (MTBE + isooctane) were measured at four temperatures from (298.15 to 328.15) K, and the respective values of excess volumes VE m and adiabatic compressibility jS were calculated. The VE m and jS values were fitted to the fourth-order Redlich Kister equation. The VE m values for (MTBE + toluene) are negative and decreasing with increasing temperature. The other systems show positive VE m with comparatively small temperature dependence.
