Investigation of Solubility Behavior, Data Correlations and Thermodynamic Study of Succinic Acid in Water + Methanol Mixtures at Various Temperatures

By using a gravimetric approach, the solubility of succinic acid in water, methanol, and water + methanol binary solvent was determined at temperatures between 305.15 and 313.15 K in the local atmosphere. The findings of the experiment demonstrated a positive correlation between temperature rise and succinic acid solubility. In order to better correlate and match the experimental results, the thermodynamic models van't Hoff and Apelblat were used. Additionally, the DFT investigation was conducted to look into how solvent-solute interactions affected solubility. In addition, the dissolving process's thermodynamic characteristics were computed, and the findings suggested that it was an entropy-driven, spontaneous, endothermic process.
