Simultaneous correlation of VLE and LLE experimental data for system with upper critical solubility temperature (tetraglyme ? decane)

Original language description

Properties related to vapor-liquid and liquid-liquid equilibria have been measured, collected from literature and subsequently simultaneously correlated using Redlich-Kister equation for the binary system Tetraglyme + Decane. IGS method was used for measurement of limiting activity coefficients of alkanes (C5-C8) in Tetraglyme in temperature interval (288.15K ? 313.15K) and limiting activity coefficient of Decane in Tetraglyme was subsequently obtained by extrapolation in a homologous line. LLE was measured by direct analytical and turbidity methods. Excess enthalpy and excess heat capacity data were collected from literature. The studied system shows upper critical solubility temperature and ?M-shape? of excess heat capacity concentration dependence and therefore high number of correlation equation parameters was needed for a precise description of temperature and concentration dependence of Gibbs excess energy and related physical properties.
