Isobaric Vapor−Liquid Equilibria for the Binary Mixtures of Styrene with Ethylbenzene, o-Xylene, m-Xylene, and p-Xylene

Consistent vapor−liquid equilibria (VLE) data have been determined at (5 and 15) kPa for the binary systems styrene + ethylbenzene, + o-xylene, + m-xylene, and + p-xylene in the temperature range (324 to 359) K. The binary systems exhibit very slight deviations from ideal behavior, and no azeotrope is present. The VLE data were well-correlated by the Wilson, NRTL, and UNIQUAC equations.
