Intermolecular Interactions in Liquid Ethanol-Dioxane Mixtures

Abstract

The ¹H-NMR spectra of liquid mixtures, ethanol (EtOH)-dioxane
(Dx), were recorded at 293.15 K within nearly the whole range of
the mixed solvent compositions. From these data the values of
the spectral parameter, Δδ(EtOH-Dx) were found. The densities,
volumes and viscosities of the mixed solvents were measured
at 293.15 K. From all these new parent data, the values of molar
volumes (V₁₂), viscosities (η₁₂) and their deviations from
"ideality" were calculated. the scrutiny of all these structural
parameters as functions of the mixture composition points to
the formation of a "complex" (sub-unit) of the EtOH·2Dx and
2EtOH·3Dx types.
