Vapor-liquid equilibrium of benzene-biphenyl Waldichuk, Michael


A comprehensive survey has been made of vapor liquid equilibrium apparatuses in the light of historical development. Two of the better types of units have been chosen and built for this research. The vapor liquid equilibria of benzene-n-butanol and benzene-biphenyl were determined on the Gillespie-Fowler equilibrium still. Thermodynamic consistency of the results was checked with the van Laar and Margules integrations of the Gibbs Dubem equation. Results obtained on the benzene-n-butanol system appear to conform to theory within experimental error. However, those of benzene-biphenyl show very little consistency. Temperature-Composition diagrams were drawn for both systems and follow the general form for non-azeotropic mixtures.
