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 VmE and adiabatic compressibility κ S were calculated. The VmE and κ S values were fitted to the fourth-order Redlich–Kister equation. The VmE values for (MTBE + toluene) are negative and decreasing with increasing temperature. The other systems show positive VmE with comparatively small temperature dependence.
