Solid-liquid equilibrium and excess enthalpy measurements in binary {dibenzofuran or xanthene plus normal long-chain alkane} systems
This paper is a continuation of our previous studies on thermodynamic properties of binary systems formed by a long-chain n-alkane and a polyaromatic. Solid-liquid equilibrium and enthalpies of mixing data of the following systems were measured: {dibenzofuran (DBF) (CASRN 132-64-9), C12H8O + eicosane (CASRN 112-95-8), C20H42}, {DBF + pentacosane (CASRN 629-99-2), C25H52}, {DBF + octacosane (CASRN 630-02-4), C28H58}, {DBF + hexatriacontane (CASRN 630-08-6), C36H74}, {xanthene (CASRN 92-83-1), C13H10O + eicosane}, {xanthene + octacosane}, {xanthene + hexatriacontane}. All data were correlated using the group contribution model based on the lattice theory of Kehiahian et al. (J. Chim. Phys. 1978, 75, 1032-1048).
