Vapour—liquid equilibria of the system cyclohexane—methanol: ebulliometric method

Abstract

The experimental determination of vapour—liquid equilibrium using a recirculating type still entails the difficulty and uncertainty of analysis of compositions of liquid and vapour samples. An ebulliometer in many cases, dispenses with this difficulty and with a proper and accurate method for correlating the data, a considerable amount of time is saved without sacrificing the accuracy of results. In this brief communication, liquid—vapour equilibrium data are reported for the system methanol—cyclohexane at 45°, 55°C, and 760 mm of Hg total pressure from ebulliometric measurements.
