Abstract

The vapor-liquid equilibria behavior of two ternary mixtures, water-formic acid-acetic acid and water-acetic acid-propionic acid, was studied experimentally in a Dvorak and Boublik recirculation still at 760 mmHg. A ternary saddle point azeotrope exists in the first mixture which boils at 107.0 °C and contains 36.3 mole % water, 46.9 mole % formic acid, and 16.8 mole % acetic acid. No ternary azeotrope exists in the second mixture. A thermodynamic model suggested in the past, which accounts for nonideal gas behavior and association effects in a multicomponent mixture, was applied for analysis of the data.
