TL;DR: In this article, a novel approach is presented for predicting the values of freezing point depression and boiling point elevation for electrolyte solutions at different concentrations on the basis of the Pitzer theories.
Abstract: A novel approach is presented in this work for predicting the values of freezing point depression and boiling point elevation for electrolyte solutions at different concentrations on the basis of the Pitzer theories. This method treats the enthalpy change of the solution between the normal freezing point or boiling point and the real ones to be linear temperature dependence. Compared with the literature values, this method performs very well; also, the temperature-dependent parameters of some salts are incorporated to investigate temperature effects of this method. Furthermore, a method based on the Clausius−Clapeyron equation is derived for estimation of the enthalpy of vaporization of very high concentration solutions at different temperatures, and the predicted results are highly positive.

TL;DR: In this paper, an application of the Pitzer method for calculating the activity coefficients to the estimation of the boiling point rise of single component and multicomponent electrolyte solutions is presented.
Abstract: The boiling point rise (elevation) of aqueous industrial solutions is often regarded as an important property with respect to chemical process design. This work shows an application of the Pitzer method for calculating the activity coefficients to the estimation of the boiling point rise of single-component and multicomponent electrolyte solutions. Good agreement between experimental and predicted values of the boiling point elevations of solutions of several salts (NaOH, Na2CO3, Na2SO4, NaCl, Na2S2O3, Na2S, mixed NaOH−Na2CO3, and mixed Na2CO3−Na2SO4) was obtained. A method for using the boiling point rise data to obtain ionic interaction parameters for the Pitzer method is also shown.

TL;DR: In this article, the authors measured the viscosity of acetone-water liquid solutions over the entire concentration range at temperatures from 20°C. to generally within 1° to 10°C of the normal boiling point.
Abstract: The viscosity of acetone-water liquid solutions has been measured over the entire concentration range at temperatures from 20°C. to generally within 1° to 10°C. of the normal boiling point. A capillary suspended-level viscometer was used, and the authors estimate that the results are accurate to ±0.2%. Both kinematic and absolute viscosities are given, and the results have been extrapolated to the boiling point of the solutions. The calibration of the Cannon-Ubbelohde viscometer is discussed in detail.
