Isobaric Vapor−Liquid Equilibria for Water + Acetic Acid + Lithium Acetate

subject

description

Isobaric vapor−liquid equilibria for all of the binary and ternary mixtures of water, acetic acid, and lithium acetate have been measured at 100.00 kPa using a recirculating still. To take into account the association of the acetic acid in the vapor phase, Marek's chemical theory has been considered. The three experimental binary data sets have been independently correlated using Mock's electrolyte NRTL model, and the binary parameters estimated for each binary system have been used to predict the ternary vapor−liquid equilibrium using the same model. No ternary parameters were required. The ternary equilibrium values obtained in this way agreed well with the experimental values.
