Solubilities of Succinic Acid in Acetic Acid + Water Mixtures and Acetic Acid + Cyclohexane Mixtures

Abstract

The solubilities of succinic acid in acetic acid + water solvent mixtures at (303.2 to 333.2) K and acetic acid + cyclohexane solvent mixtures at (303.2 to 343.2) K were determined. It was found that the solubility of succinic acid in acetic acid + cyclohexane mixtures increases with increasing mass fraction of acetic acid at constant temperature. However, for the system of acetic acid + water solvent mixtures, acetic acid with the mass fraction of 0.20 shows the best dissolving capacity for succinic acid. The experimental data were well-correlated with universal quasi-chemical (UNIQUAC) equations, and the solubilities calculated by the model were in good agreement with experimental data.

Measurement and Correlation for the Solubility of Adipic Acid and Succinic Acid in Glutaric Acid + Cyclohexanone and Glutaric Acid + Acetic Acid Mixtures

“…To verify the accuracy and reliability of the experimental apparatus and experimental method, the determined solubility of AA and SA in cyclohexanone and HAc would be compared with the published data reported. [13][14][15][16][17]19,21,23 As shown in Figures 2 to 5 and Table 2, the experimental measured solubility was in good agreement with the available literature reported data, which indicates the accuracy and reliability of our experimental technique. 3 and summarized in Figures 6 and 7, in which ω 1 is the mass fraction of GA in GA + cyclohexanone and GA + HAc solvents and x represents the mole fraction solubility of AA in solvent mixtures.…”

Solubility of Thiamine in Pure and Mixed Solvents in Function of Temperature

“…This is common behavior among vitamins as observed in the literature 7 . Additionally, it is observed that thiamine solubility also increases with increasing temperature, as observed in the literature 7,[12][13][14] . An adequate relationship between the experimental results and the results described by the fitting models was observed.…”

Hence, it is essential to measure and correlate the solubilities of AA, GA, and SA in DMA + methanol solvent mixtures, respectively.…”
