ABSTRACT
Liquid-liquid equilibria data including the tie-lines for ternary systems formed by oligooxaethylenes with ethanol and hexadecane are measured at two temperatures. The liquid-liquid measurements were made for the 2,5,8,11-tetraoxadodecane + ethanol + hexadecane system at (293.15 and 298.15) K and for the 2,5,8,11,14-pentaoxapentadecane + ethanol + hexadecane system at (298.15 and 303.15) K. These systems are characterized by the band type miscibility gap for two measured isotherms, where two binaries are partially miscible. Experimental data are smoothed by means of the correlation equation proposed by these authors similar to the Redlich and Kister equation.
