Both mixtures yield an azeotrope, the compositions (ester) of which decrease quasi‐linearly as the pressure increases. The experimental data for all the binary mixtures were fitted to a suitable equation and then used for comparison with predictions by ASOG and UNIFAC methods. These group contribution models give a good estimation of activity coefficients with an overall mean error less than 5% for all cases.||URI:||http://hdl.handle.net/10553/53813||ISSN:||0008-4034||DOI:||10.1002/cjce.5450690150||Source:||Canadian Journal Of Chemical Engineering[ISSN 0008-4034],v. 69 (1), p. 394-397|
