Diffusion in Glycerol-Water Mixture

摘要: Diffusion studies of glycerol in glycerol-water mixtures ranging from zero to 93% were carried out using the microinterferometric method. For higher concentration diffusion coefficient decreases strongly with increasing and curves are highly skewed. Applying thermodynamic hydrodynamic correction obtained vapor pressure measurements solution viscosities, respectively, was found be sensibly independent up about 70% after which it rises. The increased mobility at very high concentrations is attributed a decreased hydration molecules under these conditions.
