Abstract
A Differential Scanning Calorimetry (DSC 7, Perkin-Elmer) is used to determine the solid- liquid phase diagram for polycyclic aromatic compounds of biphenyl and 2,3-dimethylnaphthalene. The eutectic temperature is also measured. In this work, the experimental diagram cmpared satisfactorily with group contribution models, Modified UNIFAC (Lyngby and Dortmund versions).
