Measurement and Correlation of the Densities and Viscosities of 2-Bromopropane plus Ethanol Binary Mixtures at Temperatures from (298.15 to 318.15) K
The densities and viscosities of 2-bromopropane + ethanol binary mixtures had been determined using an digital vibrating U-tube densimeter and Ubbelohde capillary viscometer respectively from (298.15 to 318.15) K. The dependence of densities and viscosities on temperature and concentration had been correlated. The excess molar volume of the binary system was calculated from the experimental density data. The excess molar volumes were related to compositions by polynomial regression and regression parameters, and total rmsd deviations were obtained. The results showed that the model agreed very well with the experimental data.
