Measurements of liquid-liquid equilibria for quaternary mixtures of water, methyl tert-butyl ether, and diisopropyl ether with methanol or ethanol
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.
