摘要：

Some thermodynamic properties (excess enthalpies, entropies and Gibbs energies of mixing) have been determined for binary solutions of ethylbenzene + n-alkanes (eicosane, C20H42; heneicosane, C21H44; docosane, C22H46; tricosane, C23H48; and tetracosane, C24H50), at crystallization temperatures in the (260-305) K range. The calculated properties vary with the chain lengths of the n-alkanes, and show the alternation effect occurring in the general behaviour of n-alkanes. Simple analytical expressions have been established to describe the excess properties. (C) 1997 Elsevier Science B.V.
