Solid-liquid equilibria of acenaphthene with o-, m-, or p-dichlorobenzene
A differential scanning calorimetry (DSC) was used to determine binary solid-liquid equilibria (SLE) for acenaphthene + o-dichlorobenzene, +m-dichlorobenzene. and +p-dichlorobenzene over the whole concentration range. It was found that all systems are simple eutectic systems. The eutectic point of the (acenaphthene + o-dichlorobenzene) system is at 254.95 K and 0.0334 mole fraction of acenaphthene, that of the (acenaphthene + m-dichlorobenzene) system at 246.15 K and 0.0460 mole fraction of acenaphthene and that of the (acenaphthene + p-dichlorobenzene) system at 307.75 K and 0.2940 mole fraction of acenaphthene. Furthermore, the activity coefficients of the components in the 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. (C) 2009 Elsevier B.V. All rights reserved.
