Experimental VLE at 101.32 kPa in binary systems composed of ethyl methanoate and alkan-1-ols or alkan-2-ols and treatment of data using a correlation with temperature-dependent parameters

New experimental VLE data of five binary ethyl methanoate+alkan-1-ol or +alkan-2-ol mixtures are presented which have been obtained isobarically at 101.32 kPa using a dynamic equilibrium apparatus. All systems verify the thermodynamic consistency with one version of the point-to-point test and present a positive deviation from ideality in almost all concentration range. Several equations are used in the treatment of VLE data, and a new correlation employed in this work using temperature-dependent coefficients appear to be also suitable. Activity coefficients calculated from experimental data have been compared with predictions of several group contribution models giving place to a mean error less than 7%. The azeotrope experimentally detected in the mixture ethyl methanoate(1)+ethanol(2) at x1=0.956, T=327.2 K was also well predicted by the versions used of UNIFAC.
