Mutual diffusion coefficients of aqueous solutions of some glycols

Mutual diffusion coefficient data for aqueous solutions of some glycols (ethylene glycol, diethylene glycol, triethylene glycol and tetraethylene glycol) were measured using Taylor dispersion method, for each binary aqueous glycol solution, at different concentrations and temperatures. The measured...

Description
Summary:Mutual diffusion coefficient data for aqueous solutions of some glycols (ethylene glycol, diethylene glycol, triethylene glycol and tetraethylene glycol) were measured using Taylor dispersion method, for each binary aqueous glycol solution, at different concentrations and temperatures. The measured data were fit to different models empirical and semi-theoretical models and compared with the values predicted from such models. The results are presented and discussed in this paper.
