Resumen: This article is a theoretical-experimental study on the binary systems ethyl methanoate + alkanes (hexane to decane). Vapour-liquid equilibrium (VLE) data at a pressure of 101.32 kPa are presented for the five systems studied and all were consistent with a point-to-point test. The only azeotropic binary system is ethyl methanoate + hexane, with azeotropic coordinates at x(az) = 0.709, T-az = 323.21 K. Also, for the same group of systems the excess properties H-m(E) and V-m(E), measured at 318.15 K, are presented and an interpretation of the results obtained for these is carried out. The excess properties are correlated with a new polynomial equation that is also proposed for the treatment of equilibrium data and is included as an acceptable part of a more complete data processing.For the five binary mixtures studied, the equilibrium thermodynamic property estimation for several group contribution models is performed.
