Abatraot

-Mutual solubility and tie-line data are presented for rriz ternary liquid-liquid systems containing acetone, water, and the estera methyl acetate, ethyl acetate, propyl acetate, amyl acetate, ethyl propionate and ethyl butyrate at 80°C. For comparison, equilibrium data for the system acetone-water-n-butyl acetate reported in literature has been plotted on the mutual eolubility, equilibrium distribution and selectivity diagrams. The tie-line data for the siz systems have been correlated satiefact.orlly by the methods of HAND and GTIXMEB and TOBLU and the plait pointa are located by the method of TREYBAL, Wnmm and D-Y.

From the comparative plot of the distribution of acetone between the eater and aqueous layers for the various systems, it is found that acetone favomz the ester layer in all the cases. The system, propyl acetateaoetone-water is observed to exhibit solutropy. Among the various esters studied, amyl acetate irr observed to be the meet selective of all the solvents. * d.i. die Stelle der Bmodalkurve, an der die Konnoden zu einem Punkt zusammenhxufen.
