Vapour-liquid equilibria XI. The quaternary system cyclohexane + hexane + acetone + methanol at 313.15 K

Total vapour pressure measurements made by the modified static method for the quaternary system cyclohexane + hexane + acetone + methanol at 313.15 K are presented in addition to previously published data for the constituent binary and ternary systems. The different expressions for GE suitable for prediction of the quaternary VLE from constituent binaries are studied.
