Abstract

New data of the vapor-liquid equilibria of the ternary systems tert-butyl alcohol diethyl ketone-methyl Isobutyl ketone and diethyl ketone-methyl isobutyl ketone-n-butyl alcohol and their binaries were obtained at 760 mmHg. The activity coefficients were satisfactorily correlated according to the Redlich-Kister equation and the behavior of the ternary mixtures could be predicted from the binary data. Boiling points of the mixtures were correlated weli by an empirical correlation and could be predicted within a mean error of 0.07-0.7 %. The ternary systems do not exhibit azeotropic behavior. The binary system methyl isobutyl ketone-n-butyi alcohol forms an azeotrope that boils at 113.28 ΔC and contains 63.3 moi % methyl isobutyi ketone.
