ABSTRACT

Experimental isobaric vapor liquid equilibrium data for the binary systems, diisopropyl ether + isopropyl alcohol and methanol + diisopropyl ether at the local atmospheric pressure of 94.79 kPa and at subatmospheric pressures of (53.3, 66.7, 79.9) kPa were obtained over the entire composition range using a Sweitoslawsky-type ebulliometer. The experimental temperatures were compared with predictions made using Wilson, NRTL, UNIQUAC, UNIFAC, Peng Robinson (PR) and Soave Redlich Kwong (SRK) equations of state (EoS) with Wong Sandler (WS) mixing rules. Model parameters along with the deviations in temperature have been presented. Experimental temperatures were found to be in good agreement with the predicted values. NRTL model was found to represent the VLE behavior of these systems better than the other models used. Density and refractive indices of mixtures are reported from 293.15 K to 318.5 K.
