The solubility of 2-aminobenzamide in 15 pure organic solvents, including methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, n-pentanol, isopentanol, n-hexanol, n-octanol, acetone, ethyl acetate, acetonitrile, tetrahydrofuran, and methyl acetate, was measured using a gravimetric method over the temperature range from 273.15 to 324.15 K under atmosphere pressure. Four thermodynamic models, that is, Apelblat equation, λh equation, nonrandom two-liquid equation, and Wilson equation, were applied to correlate the measured solubility data. The correlation results were evaluated by the relative average deviation. The results indicated that the mole fraction solubility increased with the rising of temperature in all 15 solvents, and the Wilson model gave the best fitting results. The experimental data and correlation models would be useful in the purification and synthesis process of 2-aminobenzamide.
