X-Ray Study of Benzene-Cyclohexane Mixtures

X-ray diffraction patterns have been made of benzene, cyclohexane, and three mixtures. The first strong peak of the mixtures is a single peak showing no trace of resolution into a benzene peak and a cyclohexane peak. If benzene-cyclohexane mixtures have an emulsion type of structure, such as postulated by H. K. Ward, the separation of the benzene and cyclohexane peaks is too small, relative to the peak widths, to allow the two component peaks to be distinguished. X-ray studies of benzene-cyclohexane mixtures can neither prove nor disprove the existence of an emulsion type of structure in the mixture.
