摘要：
Diamines are an important group of compounds in different fields of industry and particularly in the synthesis of a number of polymers. In this work, study of binary solid-liquid equilibriums SLE for (biphenyl+4,4' diaminodiphenylmethane), and (naphthalene+4,4' diaminodiphenylmethane) systems is done by differential scanning calorimetry. Results obtained with this technique are compared with those predicted by modified UNIFAC (Larsen and Gmehling) models. It was found out that all the systems are eutectic and globally good agreement is obtained between experimental and predicted SLE.
