Liquid densities were measured by Anton Paar Density & Sound Analyzer DSA 5000 for ternary systems (toluene + isooctane + ethanol) and (toluene + isooctane + 1-butanol) as well as for all the five constituent binary subsystems, namely (toluene + isooctane), (toluene + ethanol), (isooctane + ethanol), (toluene + 1-butanol), (isooctane + 1-butanol) at four temperatures from 298.15 K to 328.15 K. In case of the ternary systems the measurements were conducted along four cuts of pseudo-binaries (toluene + isooctane) + ethanol and (toluene + isooctane) + 1-butanol, respectively. The mole fractions of isooctane in the (toluene + isooctane) mixture were approximately 0.2, 0.4, 0.6 and 0.8; ethanol or 1-butanol was then added to cover its whole molar range. The corresponding values of excess volumes were calculated from the primary density data and fitted to a modified Redlich-Kister equation.
