Equivolume mixture permittivity

Thus, permittivity of equivolume mixture of two chemically non-interacting solvents can be calculated from the equation... 

Permittivity of mixtures at different temperatures can be calculated with high accuracy from absolute temperature coefficients of permittivity and their values using equations identical in form to [8.1.24]-[8.1.26]. For example, the calculation of temperature coefficients of permittivity, a, of the equivolume mixture of two chemically non-interacting associated solvents is carried out using the equation identical in its form to [8.1.26].
