Measurement and correlation of isobaric vapor-liquid equilibria for binary and ternary systems containing Methyl Tertiary Butyl Ether (MTBE), methanol and alkanes

Isobaric vapor-liquid equilibria (VLE) of four binary systems-methyl tertiary butyl ether (MTBE)+ methanol, MTBE+heptane, MTBE+octane and MTBE+i-octane-were measured at atmospheric pressure by using Othmer-type circulation method. The VLE of a ternary system, MTBE+methanol+heptane, were also measured at atmospheric pressure. These VLE data were predicted by ASOG and correlated by Wilson equation, and the prediction and correlation performances were discussed.

Vapor-liquid equilibria for (methyl tertiary butyl ether+methanol+octane) and (methyl tertiary butyl ether+methanol+i-octane) systems at atmospheric pressure

Isobaric vapor-liquid equilibria (VLE) of two ternary systems (methyl tertiary butyl ether+methanol+ octane and methyl tertiary butyl ether+methanol+i-octane) were measured at atmospheric pressure by using a modified Othmer-type circulation apparatus. The VLE data of these ternary systems can be predicted by Wilson equation with the parameters determined by VLE data of constituent binary systems.
