For the extension of the experimental data base for the revision of already existing group interaction parameters as well as for fitting of new group interaction parameters, systematic experimental measurements are performed. For the UNIFAC Consortium delivery 2017, 17 vapor-liquid equilibrium data sets, 28 excess enthalpy data sets and 4 solid-liquid equilibrium data sets of binary systems have been measured over the whole concentration range.
