UNIFAC Matrix 2018

The diagram in this page shows the development of the interaction parameters and groups of the original UNIFAC method in the consortium from 1998 to 2018. Click or tap the diagram to see more details.

Besides the work on Modified UNIFAC (Dortmund) also the original UNIFAC method was further developed. On the basis of the increasing number of VLE and γ data not only gaps in the original UNIFAC matrix were filled but also the new groups (epoxides, anhydrides, carbonates, sulfones, acrolein, glycerol, n-formylmorpholine and diketones) were introduced. It is planned to further develop also the original UNIFAC matrix and to introduce the groups which already have been included into the Modified UNIFAC (Dortmund) matrix. The original UNIFAC is very important e.g. as a basis for the group contribution equation of state PSRK.
