AZEOTROPIC DATA FOR BINARY MIXTURES
Liquid mixtures having an extremum (maximum or minimum) vapor pressure at constant temperature, as a function of composition, are called azeotropic mixtures, or simply azeotropes. Mixtures that do not show a maximum or minimum are called zeotropic. Azeotropes in which the pressure is a maximum are often called positive azeotropes, while pressure-minimum azeotropes are called negative azeotropes. The coordinates of an azeotropic point are the azeotropic temperature t az, pressure P az , and liquid-pha composition, usually expresd as mole fractions. At the azeotropic point, the vapor-pha composition is the same as the liquid-pha composition.
This table gives azeotropic data for a number of binary mixtures at normal atmospheric pressure (P az =101.3 kPa). Component 1 of each mixture is given in bold face. The temperature t az and mole fraction x1 of component 1 are listed for each choice of component 2.
The components are arranged in a modified Hill order, with substances that do not contain carbon preceding tho that do contain carbon.
