Abstract
The solid−liquid equilibrium data of 4-formylbenzoic acid in four solvents was measured by the steady-state method at temperatures ranging from (303.2 to 473.2) K, including ethanoic acid, water, and aqueous ethanoic acid with 0.8 and 0.9 mass fractions of ethanoic acid, respectively. The solubility model modified from the Apelblat equation was used to correlate the experimental data. The average relative deviations of these correlations are 0.06 and 0.04 for solubilities in ethanoic acid and water at temperatures above 403.2 K, respectively, and no more than 0.03 for those in aqueous ethanoic acid.
