✦ Synopsis

Abstraet-Experimental molecular ditfusivity data were obtained for two ternary liquid systems with a dilute solute diffusing in a very non-ideal solvent mixture and a second dilute solute in a viscous solvent mixture using the diaphragm-cell method. Using only the diffusion data of the solute in each of the two pure solvents and viscosity data of the mixtures, a modified equation was shown to predict the diffusion data over the entire solvent mixture concentration range. A modified Wilke-Chang type equation was also used.
