ESTIMATION OF ENTHALPIES OF FUSION, MELTING TEMPERATURES, ENTHALPIES OF TRANSITION, AND TRANSITION-TEMPERATURES OF PURE COMPOUNDS FROM EXPERIMENTAL BINARY SOLID-LIQUID EQUILIBRIUM DATA OF EUTECTIC SYSTEMS

This paper presents a procedure for the estimation of enthalpies of fu sion, melting temperatures, enthalpies of transition, and transition t emperatures using experimental binary solid-liquid equilibrium data of eutectic systems and the group contribution method modified UNIFAC (D ortmund) for the calculation of the required activity coefficients. Ad ditionally, experimental solid-liquid equilibrium data of the system t etrachloromethane + m-xylene are presented.
