The Relative Permittivity of 1,2-Dimethoxyethane/Water Solvent Mixtures From -10 to 80°C

Abstract

Relative permittivities (є) and the excess property (є^E) for the binary mixtures formed by 1,2-dimethoxyethane with water have been measured at various temperatures in the range from -10 to +80°C. These mixtures have interesting properties for electroanalytical applications. Their study should help in understanding the phenomenology of cosolvency towards ionizable and inert solutes. The results of the є^E analysis are discussed in terms of the influence of interactions between the components, order and degree of packing in the mixtures, and any other structural effect which occurs in solution.
