【 摘 要 】

References(28)Cited-By(20)The vapor-liquid equilibria with chemical reaction equilibrium of a quaternary system, acetic acid-ethanol-water-ethyl acetate, were measured in an equilibrium still by the static method. The experimental data were correlated by using the modified UNIQUAC equation to satisfy the chemical equilibrium condition as well as the vapor-liquid equilibrium condition. The UNIQUAC binary parameters were obtained from experimental vapor-liquid equilibrium data with chemical reaction equilibrium in the liquid phase of the quaternary system and existing equilibrium data for the six binary and the two ternary systems. The correlations of both the vapor-liquid equilibrium and the chemical reaction equilibrium in the liquid phase were found to be in good agreement with the experimental data.
