Liquid-liquid equilibrium data for the ternary system limonene + linalool + 2-aminoethanol at 298.15. 308.15 and 318.15 K are reported. The experimental data have been correlated using UNIQUAC and NRTL equations obtaining the binary interaction parameters. Ibis last equation was used to determine binodal and spinodal curves. The second derivatives of the Gibbs free energy of mixing for binary systems were calculated with the aim to predict the slopes of the ternary tie-lines. Experimental data were also compared with the predictions of the UNIFAC group contribution method. (C) 2004 Elsevier B.V. All rights reserved.
