- Summary
- The diffusion of toluene, in two-component hydrocarbon solvent mixtures. at very dilute concentrations and at constant temperature was studied by a stirred diaphragm cell technique. The diffusion coefficient-- viscosity products, for the n-hexane --n-tetradecane, n-hexane-- cyclohexane, and cyclohexane--n-decane solvent mixtures, were best correlated as a linear function of the solvent composition expressed in mole fraction. The latter solvent mixture gave a definite minimura in its diffusion coefficient--viscosity product composition data, corresponding to a similar minimum in the viscosity versus composition data. An extensive study was made of the effect of free and forced convection resistances outside of the diaphragm. It was found that the mass transfer resistance external to the diaphragm was small (0.3 per cent of the total resistance at 350 rpm stirring speed) and was nearly a constant for all the fluids in- vestigated. Under these conditions the cell constant exhibited negligible variation with fluid properties.
