The empirical equations for estimating the diffusion coefficient in infinite solution which are presented in Reid, 1987 [reid1987] all show a linear dependency on temperature. We thus simply scale the experimentally obtained diffusion coefficient of Ferrell and Himmelblau by the temperature.
This function use an interpolation of the data by [witherspoon1965] http://dx.doi.org/10.1021/j100895a017
