DIFFUSION COEFFICIENTS IN LIQUIDS AT INFINITE DILUTION
This table lists diffusion coefficients D
AB
at infinite dilution
for some binary liquid mixtures . Values are given at 25°C when
available; it should be noted that the diffusion coefficient gener-
ally increases by 10% to 20% for a 10°C increase above ambient
temperature .
Solvents are listed in alphabetical order, as are the solutes within
each solvent group .
