摘要：

The liquid-liquid equilibria of the mixtures {methyl acetate + methanol + n-alkane (C-10-C-12)} at atmospheric pressure in the temperature range (278.15 to 308.15) K are presented. The equilibrium compositions were measured by gas chromatography from samples splitted isothermally into a glass-stirred device and phase diagrams are reported at each temperature. The experimentally determined liquid-liquid equilibria were satisfactorily correlated by the NRTL and UNIQUAC equations. A poor description has been obtained using the UNIFAC method and their modifications. (C) 2004 Elsevier Ltd. All rights reserved.
