Vapor-Liquid and Liquid-Liquid Equilibria for Binary and Ternary Systems Containing Methanol

Abstract

Vapor-liquid and liquid-liquid equilibrium data at 25°C are presented for ternary and constituent binary systems containing methanol, cyclohexane and carbon tetrachloride, in which a two-liquid region exists between methanol and cyclohexane.
Equilibrium data of both kinds at 25°C are also obtained for the two binary systems methanol-iso-octane and methanol-n-heptane, which have a miscibility gap in each liquid phase.
These vapor-liquid equilibrium data were obtained by static equilibration in the presence of diluent nitrogen by chromatographic analysis of the saturated vapor.
