Magneto-optical rotation studies of the structural properties of liquid mixtures. Part 2.—Binary mixtures of some miscible organic components

Abstract

Measurements have been made of the magneto-optical rotations at 435.8 nm of the following binary liquid mixtures: EtOH + cyclohexane, t-BuOH + cyclohexane, MeOH + CCl₄, MeOH + dioxan, t-BuOH + dioxan, t-BuCl + dioxan, THF + dioxan, acetic acid + dioxan, cyclohexane + 1,2-dichloroethane, benzene + 1,2-dichloroethane, toluene + 1,2-dichloroethane, CCl₄+ 1,2-dichloro-ethane, benzene + toluene, cyclohexane + CCl₄, benzene + CCl₄, toluene + CCl₄, cyclohexane + chlorobenzene, benzene + chlorobenzene, toluene + chlorobenzene, benzene +p-chlorotoluene, toluene +p-chlorotoluene. The departure from ideality of each system was treated in terms of an excess magnetic rotation, α^E, and for many systems the variation of α^E with composition gave distinct indications of specific interaction between the components of the mixture.
