ABSTRACT

Isobaric vapor-liquid equilibrium (VLE) data for the systems dimethyl carbonate (DMC) + methanol, DMC + methanol + tetramethylammonium bicarbonate (TMAB) at 101.32 kPa and the bubble point data of the methanol + TMAB system have been measured with a modified ebulliometer. The addition of the organic salt has the salting-out effect on DMC and the effect is enhanced with the increasing salt concentration. The VLE data of the salt-containing system are predicted by the modified Wilson and NRTL models proposed by Tan. The average errors for the mole fraction of the vapor phase and the bubble point by the modified predictive model were: Ay = 0.0108, AT = 0.57 K.
