VAPOR-LIQUID-EQUILIBRIUM DATA, AT 298.15-K, FOR 6 BINARY-SYSTEMS CONTAINING METHYL ACETATE OR METHANOL, WITH ACETONITRILE, NITROMETHANE OR NITROETHANE

Isothermal vapor-liquid equilibria were measured at 298.15 K for the systems containing methyl acetate or methanol with the three nitrogen compounds acetonitrile, nitromethane and nitroethane, The experimental data satisfy the Redlich-Kister thermodynamic consistency test. The liquid-phase activity coefficients were fitted by using the van Laar, Mato, NRTL, Wilson and UNIQUAC equations. The systems with methyl acetate present slight positive deviations from ideality while the systems containing methanol exhibit strong positive deviations.
