Transcription of Azeotropic Data for Binary Mixtures
1 Azeotropic DATA FOR Binary MIXTURESL iquid Mixtures having an extremum (maximum or minimum) vapor pressure at constant temperature, as a function of composition, are calledazeotropic Mixtures , or simply azeotropes. Mixtures that do not show a maximum or minimum are called zeotropic. Azeotropes in which the pressureis a maximum are often called positive azeotropes, while pressure-minimum azeotropes are called negative azeotropes. The coordinates of anazeotropic point are the Azeotropic temperature taz, pressure Paz , and liquid-phase composition, usually expressed as mole fractions. At the azeotropicpoint, the vapor-phase composition is the same as the liquid-phase table gives Azeotropic data for a number of Binary Mixtures at normal atmospheric pressure (Paz = kPa).
