ABSTRACT

(Solid + liquid) equilibria (SLE) have been measured for phenanthrene + o-dichlorobenzene, phenanthrene +m-dichlorobenzene and phenanthrene + p-dichlorobenzene using differential scanning calorimetry (DSC) over the whole concentration range. It was found that all systems are simple eutectic systems. The eutectic point of (phenanthrene + o-dichlorobenzene) mixture is at .25.0 .C and 0.0767 mole fraction of phenanthrene, (phenanthrene +m-dichlorobenzene) mixture at .28.0 .C and 0.0530 mole fraction of phenanthrene and (phenanthrene + p-dichlorobenzene) mixture at 33.6 .C and 0.3060 mole fraction of phenanthrene. Furthermore, the activity coefficients of components in binary mixtures have been correlated by the Scatchard.Hildebrand expression with one adjustable parameter. This approach offers a useful procedure for estimating with good accuracy.
