“…But chief among them were the properties of the solute and solvent, such as molecular weight, polarity, and hydrogen bonding. Differences in solute solubility in organic solvents were often related to the polarity of the solvent . According to the principle of similarity compatibility, the closer the polarity of the solute to the solvent and the closer the electronegativity, the greater the solubility of the solute in the solvent.…”

In this work, the solubility of Fe(acac) 3 (acac = acetylacetone) in five organic solvents (n-propanol, diethyl ether, ethyl acetate, tetrahydrofuran, ethanol), Fe(acch) 3 (acch = 2-acetylcyclohexanoate) in five organic solvents (acetonitrile, diethyl ether, ethyl acetate, methyl acetate, ethanol) and Fe(ba) 3 (ba = benzoylacetone) in four organic solvents (acetonitrile, diethyl ether, ethyl acetate, methyl acetate) were determined from 268.15 to 298.15 K by static analysis. The measured results demonstrated that the solubility data increased with increasing temperature. Solubility for the complexes was related using five thermodynamic models. Among them, in terms of empirical models, the Apelblat model was broadly applicable and had an average ARD of less than 3%. The activity coefficient model (NRTL model) had a good fit effect with an average ARD of less than 1.5%. Furthermore, the molecular electrostatic potential (ESP) of iron(III) β-diketonate compounds reflected that O atoms readily formed hydrogen bonds. Hirshfeld surface analysis revealed that the largest contact rate was in the H•••H contact.

“…Solubility depends on many factors, including the physical properties of the solvent and the nature of the solute itself. According to the concept of “like dissolves like”, solutes and solvents are more soluble when they have similar polarities. , In this paper, the order of polarity of the solvents is acetonitrile > N , N -dimethylformamide >1, 2-dichloroethane > dichloromethane > tetrahydrofuran. The low solubility of L 1 in the two more polar solvents, acetonitrile and DMF, and the relatively higher solubility in dichloromethane, tetrahydrofuran, and 1, 2-dichloroethane may be attributed to its lower polarity.…”

In this work, a static analysis method was used to measure the solubility data of L 1 (1) (L 1 = 2, 6-bis{1-[(2isopropylphenyl)imino]ethyl}pyridine) in five pure solvents, andBased on the results of the experiment, it was concluded that the solubility of the three complexes also increased as the temperature increased. Eight thermodynamic models were used to correlate experimental solubility data. The results yielded a good fit with an average absolute relative deviation (ARD) of less than 3.5% and an average root mean square deviation (RMSD) of less than 0.15% for these models. In addition, the range of molecular electrostatic potentials of the three compounds was obtained by molecular electrostatic potential analysis. Reasons for solubility differences were analyzed by calculating the Hansen solubility parameters of L 1 . The solubility data measured in this paper can provide a theoretical basis and reference standard for the selection of reaction and recrystallization solvents in future experiments.
