摘要：

Solubilities of five polycyclic aromatic hydrocarbon solids: naphthalene, acenaphthene, anthracene, phenanthrene and pyrene in n-octadecane (OD) have been determined over a range of temperatures. Differential scanning calorimetry (DSC) has been used to investigate solid-liquid equilibria. Furthermore, the activity coefficients of the aromatic hydrocarbons in OD have been correlated by Wilson's equation and by the Scatchard-Hildebrand solubility parameter expression. Both approaches offer a useful procedure for estimating, with good accuracy, activity coefficients for aromatic-saturated hydrocarbon systems.
