As the question asks, these two kinds of aniline are separated by distillation. What thermodynamic method is used when calculating with aspen? Also, are these two substances in the aspen database? I haven't found it yet. Can that friend help me? Thank you! Urgent need.

Try IDEAL, NRTL, and Wilson respectively to see which result is close to the experimental value.

Try NRTL or Wilson. If there are binary parameters displayed in parameter/binary, then it is OK. If not, select the database again and see if it will appear. If not, choose Unifac, but check to see if there are functional groups with the correct realistic composition.
