✦ Synopsis

Isobaric vapour-liquid equilibrium data of the ternary system benzene-cyclohexanemethyl isobutyl ketone were determined at '7'60 mm Hg total pressure using a modified Colburn still. The activity coefficient data for all the experimental points were correlated satisfactorily by Wohl's three suffix Margules ternary equations with a ternary constant. It was concluded that methyl isobutyl ketone might be used as an entrainer in the separation of benzene-cyclohexane mixtures into pure components.

No ternary azeotrope was observed.

Vapour-liquid equilibrium data for the systems : methyl ethyl ketone-eyclohexane and acetone-cyclohexane are determined at 760 mm Hg. It is found that methyl ethyl ketonecyclohexane system forms a minimum boilii azeotrope at 52.7 mole per cent cycJohexane and 71.6X! at 780 mm. This is in close agree

Consistent (vapour + liquid) equilibrium data for the ternary system (benzene + cyclohexane + anisole) at p = 101.32 kPa are reported. The results indicate that the mixture deviates positively from ideality and that only the minimum binary azeotrope (benzene + cyclohexane) exists. The activity coeff
