In the equipment, both phases are recirculated. Its operation is a consequence of the Cotrell pump effect produced when the mixture is heated in a double-walled inverted vessel. The reliability of the apparatus is tested with the mixtures studied previously by various authors. VLE data for the binary systems of methyl acetate + methanol and the methyl acetate + ethanol at 0.5 MPa are determined. The experimental data are confirmed with the point-to-point test of van Ness, applying the Fortran program of Frendslund et al. In addition, the experimental results are compared with the UNIFAC (including different versions) and ASOG prediction models.||URI:||http://hdl.handle.net/10553/53782||ISSN:||1004-9541||DOI:||10.1016/S1004-9541(09)60159-2||Source:||Chinese Journal Of Chemical Engineering[ISSN 1004-9541],v. 18 (6), p. 1000-1007|
