The solubility of m-aminobenzoic acid (m-ABA) Form I in 12 pure solvents (methanol, ethanol, 1-propanol, 2propanol, 1-butanol, isobutyl alcohol, water, acetonitrile, acetone, methyl acetate, isopropyl acetate, 1,4-dioxane) was measured at temperatures from T = 283.15 to 323.15 K by a gravimetric method under atmospheric pressure. The mole fraction solubility values of m-ABA in these 12 solvents increase with increasing temperature in the following order: 1,4-dioxane > acetone > methanol > ethanol > methyl acetate > 2-propanol > 1-propanol > 1-butanol > isobutyl alcohol > isopropyl acetate > acetonitrile > water. The solubility of m-ABA is influenced by multiple factors, such as the hydrogen bond between the solute and solvent, solvent polarity, and the solvent−solvent interaction. The relationship between solubility and temperature was mathematically correlated by the modified Apelblat equation, van't Hoff equation, λh equation, and the Wilson model. The calculated ARD% values indicate that the correlation results are in good agreement with the experimental data. The most suitable model is the modified Apelblat equation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
