Densities and viscosities of the ternary system (ethanol + methylbenzene + 2-methyl-2-propanol) and its binary subsystems were measured at T = 298.15 and 318.15 K and atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were found with an automatic microviscometer based on the rolling ball principle. From the experimental data, the excess molar volumes (V E ) and deviations in viscosity (Δη) were derived. The binary V E and Δη data were correlated with the Redlich−Kister equation. The ternary V E and Δη data were fitted to the equation based on Cibulka and the equation of Singh et al., respectively. The values of V E and Δη were used to discuss the nature of mixing behaviors for the mixtures, and leading to these excess values is perhaps due to the complex formation and/or accommodation between molecules. To describe the ternary system, several mixtures with specially designated concentrations of 2-methyl-2-propanol were considered.

A Comprehensive Brownian Dynamics Approach for the Determination of Non-ideality Parameters from Analytical Ultracentrifugation

et al. 2019

Brownian dynamics (BD) has been applied as a comprehensive tool to model sedimentation and diffusion of nanoparticles in analytical ultracentrifugation (AUC) experiments. In this article, we extend the BD algorithm by considering space-dependent diffusion and solvent compressibility. With this, the changes in the sedimentation and diffusion coefficient from altered solvent properties at increased pressures are accurately taken into account. Moreover, it is demonstrated how the concept of space-dependent diffusion is employed to describe concentration-dependent sedimentation and diffusion coefficients, in particular, through the Gralen coefficient and the second virial coefficient. The influence of thermodynamic nonideality on diffusional properties can be accurately simulated and agree with well-known evaluation tools. BD simulations for sedimentation equilibrium and sedimentation velocity (SV) AUC experiments including effects of hydrodynamic and thermodynamic nonideality are validated by global evaluation in SEDANAL. The interplay of solvent compressibility and retrieved nonideality parameters can be studied utilizing BD. Finally, the second virial coefficient is determined for lysozyme from SV AUC experiments and BD simulations and compared to membrane osmometry. These results are in line with DLVO theory. In summary, BD simulations are established for the validation of nonideal sedimentation in AUC providing a sound basis for the evaluation of complex interactions even in polydisperse systems.
