Azeotropic Data for Binary Mixtures - WPMU DEV

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). Component 1 of each mixtureis given in bold face. The temperature taz and mole fraction x1 of component 1 are listed for each choice of component components are arranged in a modified Hill order, with substances that do not contain carbon preceding those that do contain Lide, , and Kehiaian, , CRC Handbook of Thermophysical and Thermochemical Data, CRC Press, Boca Raton, FL, Horsley, , Azeotropic Data, III, American Chemical Society, Washington, , Cx1 Water , CCl4CH2O2 Formic acid CH2O2CS2 Carbon CH3NO2CS2 Carbon methyl disulfide acid C2H4O2C4H8O21, glycol sulfide ,2-Ethanediamine C3H6OC3H6O2 Methyl formate acetate DATA FOR Binary Mixtures (continued)MolecularformulaNametaz/ Cx1-2--3- Azeotropic DATA FOR Binary Mixtures (continued)
