Abstract

The separation of isopropylacetate from a ternary mixture of isopropanol, isopropylacetate and water by azeotropic distillation requires reliable and thermodynamically consistent vapor-liquid equilibrium data. By using a single experimental vapor-liquid equilibrium datum point for each of the related binaries of the above system, it is possible to determine the binary constants of some of the integrated forms of the Gibbs-Duhem equation such as the Van Laar or Margules equation. The binary constants can be used in the ternary forms of the above equations and in conjunction with the definition of activity coefficient to generate approximate vapor-liquid equilibrium data over the entire composition range. Such data could be used for preliminary design estimates of separation columns. However, for rigorous design specifications, reliable experimental vapor-liquid equilibrium data are required. Since no published data on the above system are available, it is the purpose of this paper to furnish such data for the above ternary system, its related binaries, and correlate them in terms of activity-coefficients as a function of liquid composition.
