Typical Results for Ketones
These diagrams show the prediction results of modified UNIFAC (Dortmund) with the latest published parameters (left column) and with the new and improved parameters from the UNIFAC Consortium (right column).
The prediction of mixing enthalpies has improved as well as the prediction of the vapor-liquid equilibrium. In the third example the old parameters predicted incorrectly an azeotrope whereas the new parameters correctly determine a zeotropic mixture.
The next joint DDBST user and UNIFAC consortium member meeting is scheduled for September 22th to 23th, 2020.
