An X-Ray Study of the Structure of Liquid Benzene, Cyclohexane and Their Mixtures

Abstract

Carefully purified benzene and cyclohexane exhibit x-ray diffraction peaks corresponding to preferred spacings of 4.68A and 5.09A, respectively, which are interpreted as the effective thicknesses of the respective rings. Mixtures of these two hydrocarbons give rise to two independent diffraction peaks indicating emulsion-type solutions, in which the disperse phase is too small to show even a Tyndall effect.

Dimerization Constants from Acoustic Measurements: Solutions of Benzene, Cyclohexylamine and Aniline in Cyclohexane

“…From self-diffusion measurements it was only concluded that there are aggregates of molecules present in these solutions [ 72 ]. On the other hand, Ward interpreted the X-ray diffraction results in terms of formation of an emulsion-type solution, in which the disperse phase is too small to manifest a Tyndall effect [ 73 ].…”
