Abstract

Solubilities of L-aspartic, DL-aspartic, DL-glutaric, p-hydroxybenzoic, o-anisic, p-anisic, and itaconic acids in water were determined in the temperature range 278 to 345 K. From these solubilities the apparent molar enthalpies of solution at T = 298.15 K were derived, and these are: Δ_solH_m-(L-C₄H₇O₄N, m = 0.0379 mol · kg^-1) = 26.7 kJ · mol^-1; Δ_solH_m(DL-C₄H₇O₄N, m = 0.0590 mol · kg^-1) = 30.8 kJ · mol^-1; Δ_solH_m(DL-C₅H₉O₄N, m = 0.0965 mol · kg^-1) = 27.3 kJ · mol^-1; Δ_solH_m(p-C₇H₆O₃, m = 0.0488 mol · kg^-1) = 41.9 kJ · mol^-1; Δ_solH_m(o-C₈H₈O₃, m = 0.0197 mol · kg^-1) = 28.5 kJ · mol^-1; Δ_solH_m-(p-C₈H₈O₃, m = 0.00169 mol · kg-1) = 28.1 kJ · mol^-1; and Δ_solH_m(C₅H₆O₄, m = 0.7605 mol · kg^-1) = 33.7 kJ · mol^-1.
