Liquid–liquid equilibrium data for water + ethanol + trans-decalin: Measurement and predication

Liquid–liquid equilibrium (LLE) data for (water + ethanol + trans-decalin) were measured at atmospheric pressure and in the temperature range of 300.2–315.2 K. A type 1 liquid–liquid phase diagram was obtained for this ternary system, as (trans-decalin + water) is the only liquid pair that is partially miscible. The experimental data for this system were predicted with the UNIFAC model. The reliability of the experimental tie-line data is determined through the Othmer–Tobias plots. The root mean square deviation between the observed and calculated mole percents was 8.14%.
