Critical exponent for the viscosity of four binary liquids



Robert F. Berg, Michael R. Moldover


We have measured the viscosity of four binary mixtures near their consolute points: (1) methanol + cyclohexane, (2) isobutyric acid + water, (3) nitroethane + 3-methylpentane, and (4) 2-butoxyethanol + water. The viscosity data are consistent with the power-law divergence: eta ~ |T- Tc|^-y, with an apparent viscosity exponent in the range 0.0404
