Liquid-vapour equilibria in the iso-butanol—n-butanol, methanol—n-butanol and diethyl ether—n-butanol systems

Abstract

Because of the paucity of data on the phase behaviour of mixtures of compounds containing active or polar groups at elevated pressure, the P-V-T-x relations of the iso-butanol-n-butanol, methanol—n-butanol and diethyl ether—n-butanol systems were determined at the liquid-vapour phase boundaries from near their atmospheric boiling points to the highest temperature and pressure at which the liquid and vapour co-exist. In addition, the vapour pressures and saturated liquid and vapour densities of the pure components were determined up to their critical points. The data are presented in the form of tables and graphs. In so far as is indicated by the data, the phase behaviour of binary systems of the alcohols is the same as that exhibited by binary systems of hydrocarbons that belong to a given homologous series.
