Liquid-Vapour Equilibria. I. The Systems Carbon Tetrachloride-cyclo-hexane and Water-Acetic Acid

Abstract

An apparatus for the accurate determination of liquid-vapour equilibria is described. Data obtained with it for the system carbon tetrachloride-cyclohexane at 70 °C. and the thermodynamic functions derived from these are shown to agree with the corresponding values determined by Scatchard, Wood, and Mochel(1). Equilibrium data of the system water-acetic acid have been measured at 760 mm. Hg, particular attention being given to high acetic acid concentrations. These results are compared with published values and the excess chemical potentials of the components have been calculated.
