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 .
