Open publisher page 6 citations

Abstract

Experimental tie-line data for two quaternary mixtures of water + methyl tert -butyl ether + diisopropyl ether + methanol or ethanol were measured at 298.15 K and ambient pressure. The experimental quaternary liquid−liquid equilibrium data were successfully correlated by using a modified UNIQUAC model. The calculated results were further compared with those obtained from the extended UNIQUAC model of Nagata.
