ISOTHERMAL BINARY AND TERNARY VAPOR-LIQUID-EQUILIBRIA OF TETRAETHYLENE GLYCOL WITH N-DECANE AND 2-METHYLNAPHTHALENE AT 160-DEGREES-C

Isothermal vapour-liquid equilibria have been determined for the parti ally miscible ternary n-decane-2-methylnaphthalene-tetraethylene glyco l in the miscible region and its two constituent miscible binaries at 160-degrees-C. The mutual solubilities of n-decane-tetraethylene glyco l have been determined at 110-degrees-C for computing binary NRTL para meters. These binary parameters were used to predict and compare the t ernary experimental data. The vapour-phase compositions for the ternar y and the two binaries have been correlated by the NRTL, Wilson, UNIFA C, and three-constant Redlich-Kister models.
