Vapor−Liquid Equilibria of Binary Mixtures Containing Nitroethane with Five Alkyl Esters at 101.3 kPa

Abstract

Vapor−liquid equilibria (VLE) were measured at 101.3 kPa, in a range of temperatures from 350.28 to 387.00 K, for five binary mixtures formed by nitroethane with ethyl acetate, propyl acetate, isopropyl acetate, methyl propionate, and ethyl propionate. Calculations of nonideality of the vapor phase were made with the Soave−Redlich−Kwong equation of state. The thermodynamic consistency of the data was tested via Herington analysis. The experimental VLE data were reduced, and binary parameters for four liquid models, such as van Laar, Wilson, NRTL, and UNIQUAC, were fitted. A comparison of model performances was made by using the criterion of average absolute deviations in boiling point and in vapor-phase composition.
