Abstract
A theoretical spinodal curve for the system water + chloroform + acetic acid at 25 °C is derived using a lattice model for ternary amphiphilic solutions rodlike molecules covering the bonds of the honeycomb lattice with threebody interactions between the molecular ends associated to the same lattice site The molecular model is equivalent to the standard Ising model on the same lattice its meanfield solution is the most appropriate for reproducing by local fitting the experimental data for the binodal composition The derived spinodal curve is in very good agreement with the spinodal composition determined also in the present work from the measured diffusion coefficients recently reported for the same system
