Abstract

The dependencies of the relative permittivity ε of over 50 liquids on the pressure P, as (∂1nε/P)_T,Po, and of some 40 liquids on the (square of the) electric field E at ambient conditions, as β = [∂ε/∂(E²)]_T,Po were obtained from literature data. The function (∂ 1nε/∂P)_T,Po was fitted to a simple expression in ε and the compressibility, K_T. These data were used to obtain the limiting slope for the partial molar volumes and the electrostriction of electrolytes in various solvents.
