Popis:	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 xaz=0.709, Taz=323.21 K. Also, for the same group of systems the excess properties HmE and VmE, 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.
