Resumo

SUSIAL, P.; RIOS-SANTANA, R.  e  SOSA-ROSARIO, A.. Vapor-liquid equilibrium measurements for the binary system methyl acetate+ethanol at 0.3 and 0.7 MPa. Braz. J. Chem. Eng. [online]. 2011, vol.28, n.2, pp.325-332. ISSN 0104-6632.  http://dx.doi.org/10.1590/S0104-66322011000200017.

This paper reports experimental data of the isobaric vapor-liquid equilibria (VLE) for the mixture methyl acetate + ethanol at 0.3 and 0.7 MPa, determined using a copper still ebulliometer. The activity coefficients obtained from the experimental data were correlated by using different thermodynamic mathematical models. All the binary systems show a positive consistency when subjected to the point-to-point test of Van Ness. The prediction of VLE data obtained with the UNIFAC and ASOG methods has been verified with experimental data.

Palavras-chave : VLE isobaric data; Activity coefficient; Methyl ester; Ethanol.
