Liquid – liquid equilibria in ternary mixtures of methyl oleate + ethanol + glycerol at atmospheric pressure / Alfonsina Ester Andreatta in Industrial & engineering chemistry research, Vol. 51 N° 28 (Juillet 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 28 (Juillet 2012) . - pp. 9642-9651 Titre : Liquid – liquid equilibria in ternary mixtures of methyl oleate + ethanol + glycerol at atmospheric pressure Type de document : texte imprimé Auteurs : Alfonsina Ester Andreatta, Auteur Année de publication : 2012 Article en page(s) : pp. 9642-9651 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Atmospheric  pressure  Ternary  mixture  Phase  equilibrium  Liquid  liquid  equilibrium Résumé : The knowledge and the ability to describe the phase equilibrium behavior of systems composed of transesterification products are very important in the optimization of biodiesel production and purification process. In this work, liquid-liquid equilibrium data have been measured for the ternary system methyl oleate + ethanol + glycerol, at temperatures between 303 and 333 K. This system has not been explored before. The experimental data measured were compared with analogous ternary systems showing an increasing of the solubility regarding the systems containing methanol. The isothermal experimental data have shown a good linear fit in an Othmer-Tobias plot. The group contribution with association GCA―EoS equation of state and the A-UNIFAC model were applied to represent the phase equilibria of this ternary system. The GCA―EoS model in particular, has shown a good predictive capability.
