Densities, ρ, and dynamic viscosities, η, of triethylamine + water (TEA−W) binary mixtures have been determined experimentally in the single phase region and over the whole composition range at T = (283.15 to 291.35) K. The experimental measurements of these properties were carried out at atmospheric pressure. Results have been fitted to obtain the adjustable parameters and standard deviations between the measured and fitted values, respectively. The viscosity data have been also correlated with the equations of Grunberg−Nissan, Hind et al., Katti−Chaudhri, Heric−Brewer, McAllister, and Auslander.

Measurements of the coexistence curve of the binary-fluid mixture isobutyric acid + water with added KCl salt at various concentrations show an important dependence on the critical temperature and the critical exponent β. The phase-transition region shifts as a function of the salt concentration. The effective -critical exponent β * = (0.266-0.293) is neither compatible with the Ising value β = 0.325 nor with the Fisher renormalized value ∼ 0.365.
