“…It is important to establish a solid–liquid equilibrium model. − Most solid–liquid equilibrium models are based on vapor–liquid equilibrium mathematical models, with some modifications. , Considering the properties of the model and the nature of the measurement system, the modified Apelblat equation, the λ h equation, the van’t Hoff equation, and the NRTL equation were selected to fit the experimental data of 278.15 to 318.15 K in three binary solvents.…”

Experimental solubility data of dibenzoylmethane (DBM) in three pure solvents (ethyl acetate, acetonitrile, methylbenzene) and three binary solvents (methanol + water, ethanol + water, and isopropyl alcohol + water) were measured by the gravimetric method from 278.15 to 318.15 K under atmospheric pressure. The experimental results showed that the solubility of DBM increased with the increase of temperature. Moreover, the solubility of DBM was temperature-dependent when the type and composition of solvents remained unchanged. The solubility of DBM decreased with the increase of solvent polarity because the molecular structure of DBM was not conducive to the formation of hydrogen bonds between solute and solvent molecules. The solubilities of DBM were correlated by the modified Apelblat equation, the van’t Hoff equation, the λh equation, and the NRTL equation. The modified Apelblat model produced the best fitting results among these models.

We use literature data on solubilities of 46 compounds in the water-isopropanol (IPA) system to obtain the corresponding partition coefficients, P, for transfer from water to water-IPA mixtures. We have then used our previously constructed linear free energy equation to obtain equations that correlate log 10 P at water-IPA intervals across the entire water-IPA system. These equations can then be used to predict partition coefficients and solubilities of further compounds in the water-IPA systems at 298 K. The coefficients in our linear free energy equation encode information on the physicochemical properties of the water-IPA mixtures. We show that the hydrogen bond basicity of the water-IPA mixtures only increases slightly from water to IPA, but that the hydrogen bond acidity of the mixtures decreases markedly from water to IPA in a smooth continuous manner.We have also used data on ions and on ionic species to set out equations for the estimation of their partition coefficients from water to water-IPA mixtures. We find that for partition from water to IPA itself, log 10 P= -1.
