ABSTRACT

Liquid-liquid equilibria of ternary mixtures of monoethylene glycol (MEG) with alkanes (hexane, heptane, octane, nonane, decane, 3-methylpentane, 2,4-dimethylpentane, and 2,2,4-trimethylpentane) and water were experimentally determined under atmospheric pressure at 293 K and for two of these systems (MEG + water + hexane and MEG + water + 3-methylpentane) at several temperatures (from 273 K to 313 K). The data were correlated using the Othmer-Tobias method. Two multicomponent systems containing MEG, water, n-alkanes, and branched alkanes were measured at 293 K.
