Abstract: A new ebulliometer to determine experimental VLE data, totally constructed by P. Susial, is reported. The equilibrium chamber, made of copper, presents some necessary modifications in comparison with the glass ebulliometer made by Casiano de Afonso. The new equipment belongs to those in which both phases are recirculated. In order to verify its reliability, the apparatus was tested with mixtures previously studied by various authors. VLE data for the methyl acetate + methanol binary system at 1.0, 3.0 and 7.0 bar were determined. The experimental data have been tested with the point-to-point test of Van Ness, applying the Fortran program of Fredenslund, and have shown to be consistent. In addition, the experimental results have been compared with those obtained from the UNIFAC (including different versions) and ASOG prediction models.
