“…The experimental basis for selecting the suitable solvents for specific applications is provided by the estimation of ultrasonic velocity, density, refrective index, viscosity and their fluctuation with various proportion composition of liquid and temperature and composition [10][11][12][13][14][15][16][17][18][19][20] . Thus, analysis of molecular association in system of water and N, N-dimethylacetamide (DMA) has been attempted in this work.…”

For the binary mixture of water and N, N-dimethylacetamide (DMA), observations have been done of the ultrasonic velocity (u), density (ρ), viscosity (η) and refractive index (n) in excess of the whole composition range at various temperature. Deviation in ultrasonic velocity (Δu), excess intermolecular free length (LfE), excess acoustic impedance (ZE), excess molar volume (VmE), deviation in molar refraction (ΔRm), deviation in viscosity (Δη) and excess Gibbs' free energy of activation for viscous flow (ΔG*E) were used to investigate the intermolecular interactions present in the mixture. Derived parameters such as isoentropic compressibility (Ks), the specific heat ratio (γ), and the effective Debye temperature (ϴD) at varying concentrations of DMA have also been computed using experimental data. Various semi-empirical mixing rules have also been applied to the binary mixture. Density functional theory is utilised to optimise the geometry of DMA, DMA with water, and calculation of H-bonded intermolecular interactions.

“…This modified Pitzer model considers the existence of short-and long-range interactions described by binary and ternary parameters. The modified model has been applied to determine the different thermodynamic properties of electrolyte solutions [14][15][16]. The generated parameters are fundamental to describe, understand, and project the behavior of associated multicomponent systems [17,18].…”

This study focuses on the thermodynamic modeling of the crystallization by the drowning process for two lithium salts: lithium hydroxide (LiOH) and lithium formate (CHLiO2). The modeling involves utilizing thermodynamic properties, such as the activity, osmotic, and solubility coefficients, within the ternary systems of LiOH + cosolvent + water and CHLiO2 + cosolvent + water, as well as their respective binary constituent systems. Ethanol is chosen as the cosolvent for both salts, facilitating a comparative analysis. Given the limited availability of thermodynamic data for lithium formate with different cosolvents, the study aims to address this gap. The modified Pitzer model was employed for the modeling process, where the parameters were successfully obtained for both systems, with a deviation of less than 1%. Additionally, the mass and energy balance for the drowning-out crystallization process of both salts was performed.
