THE RELATIVE PERMITTIVITY OF 1,2-DIMETHOXYETHANE WATER SOLVENT MIXTURES FROM -10 TO 80-DEGREES-C

Relative permittivities (epsilon) and the excess property (epsilon(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-de grees-C. These mixtures have interesting properties for electroanalyti cal applications. Their study should help in understanding the phenome nology of cosolvency towards ionizable and inert solutes. The results of the epsilon(E) analysis are discussed in terms of the influence of interactions between the components, order and degree of packing in th e mixtures, and any other structural effect which occurs in solution.
