Vapor-Liquid Equilibria for the Binary Systems Isobutanol with m-Xylene, o-Xylene and p-Xylene at 101.3 kPa

摘要

Vapor-liquid equilibria were measured for binary systems of isobutanol with m-xylene, o-xylene, and p-xylene at 101.3 kPa using a recirculating still. Teh accuracy of experimental measurements was +-0.1 K in temperature, +-0.01 kPa in pressure, and +-0.001 in mole fraction. Teh results were determined to be thermodynamically consistent according to the point-to-point consistency and Wisniak tests. All the systems show moderate positive deviations from ideality. The data were correlated with five liquid-phase activity coefficient models (Margules, Van Laar, Wilson, NRTL UNIQUAC).
