Abstract

Solubilities of o-acetylsalicylic, 4-aminosalicylic, 3,5-dinitrosalicylic, and p-toluic acid, and magnesium-DL-aspartate in water were determined in the temperature range (278 to 345) K. The apparent molar enthalpies of solution at T = 298.15 K were derived from these solubilities, and the resulting values are Δ_so1H_m(o-C₉H₈O₄, m = 0.0226 mol·kg^-1) = 22.9 kJ·mol^-1, Δ_so1H_m(4-C₇H₇O₃N, m = 0.00758 mol·kg^-1) = 26.1 kJ·mol^-1, Δ_so1H_m(3,5-C₇H₄O ₇N₂, m = 0.0633 mol·kg^-1) = 28.7 kJ·mol^-1, Δ_so1H_m(p-C₈H₈O₂, m = 0.00258 mol·kg^-1) = 24.0 kJ·mol^-1, and Δ_so1H_m(DL-C₈H₁₂O ₃N₂Mg, m = 0.1485 mol·kg^-1) = 11.7 kJ·mol^-1.
