ABSTRACT

Ternary liquid liquid equilibrium (LLE) data were measured and correlated for the water + acetonitrile + (butan-1-ol or 2-methylpropan-1-ol) systems at (303.2, 323.2, and 343.2) K and 1 atm. A double-walled glass cell with the direct analytical method was used to measure the liquid liquid equilibrium data. The phase equilibrium samples were analyzed and quantified using gas chromatography. The nonrandom two-liquid activity coefficient model was used to fit the experimental tie-lines using nonlinear least-squares regression of the data. Relative selectivity values for solvent separation efficiency were calculated from the tie-line data. The plait point for each temperature was estimated with the graphical Coolidge method.
