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, KT. These data were used to obtain the limiting slope for the partial molar volumes and the electrostriction of electrolytes in various solvents.
