Refractive indices of binary mixtures of (1,2-dichloroethane + 2-chloroethanol) at various temperatures

Measurements of the refractive index n(D) of(1,2-dichloroethane + 2-chloroethanol) in the temperature range 273.15 K less than or equal to T less than or equal to 343.15 K have been carried out for the purpose of checking the suitability of some empirical models of the type n(D) = n(T), n = n(x(i)), and n = n(T, x(i)) for the correlation and interpolation of experimental data to cover existing gaps. Furthermore, the experimental data have been used to calculate excess properties such as Delta n(D), R-E, and the excess Kirkwood parameter ag over the entire composition range. The results obtained have been discussed and interpreted in terms of the type and nature of the specific intermolecular interactions between the components.
