LIQUID LIQUID EQUILIBRIUM OF WATER + 2-PROPANOL + 2,2,4-TRIMETHYLPENTANE TERNARY AT 293.2+/-0.1 K

Abstract

Tie-lines and the isothermal solubility curve of water + 2-propanol + 2,24-trimethylpentane were experimentally determined at 293.2 +/- 0.1 K. The reliability of tie-line measurements was checked via Campbell's method and the correlation using Hand's equation. Tie-lines were predicted from the liquid-liquid equilibrium data UNIFAC model. The extracting capability of 2,2,4-trimethylpentane for separating 2-propanol from its aqueous solutions was investigated in terms of distribution coefficients, separation factors and selectivity.
