ABSTRACT
Vapor-liquid equilibria at 94.4 kPa, over the entire composition range, were measured for the binary mixtures hexane (1) + N,N-dimethyl formamide (2), 2-methylpropan-2-ol (1) + 2-aminoethanol (2), 2-methylpropan-2-ol (1) + N,N-dimethyl formamide (2), and 2-propanol (1) + diisopropyl amine (2). A Swietoslawski-type ebulliometer was used to measure the bubble point temperatures necessary to determine the vapor-liquid equilibrium. The Wilson equation was used to represent the measured liquid-phase composition versus temperature data. Values of the vapor-phase mole fraction, activity coefficients, and excess Gibbs energy computed from the model are also presented and discussed.
