This paper presents the results of a liquid-liquid equilibrium data correlation for 11 ternary systems which have not been previously fitted using the NRTL model or, when they have, the results presented in the literature are inconsistent with the experimental behavior of the system. These ternary systems include mixtures with one or two partially miscible pairs. During the correlation process, new restrictions were imposed on the values for the NRTL binary parameters to ensure correct prediction of the total or partial miscibility for the binary pairs involved. In addition. topological concepts related to the Gibbs stability test have been applied in order to validate the results in the whole range of compositions. (C) 2008 Elsevier B.V.
