Abstract
Densities, viscosities, and surface tensions have been measured for n-octanol-phosphoric acid solutions in the range from x 1 = 0 to 0.0266 and temperature from 293.15 to 333.15 K at atmospheric pressure. The coefficient of thermal expansion, excess molar volumes and deviations of surface tension are calculated from the experimental data. The excess molar volumes and deviations of surface tensions are fitted to use the Redlich-Kister polynomial equation. According to the experimental data, the measured viscosities are well fitted to regression equation under the correlating temperature and mass fraction of phosphoric acid. The experimental and calculated thermodynamic properties can be used in research on the nature of mixing behavior of the solutions for molecular models and industrial applications.
