ABSTRACT

The solubility of 2-aminobenzamide in fifteen 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, i.e. the modified Apelblat equation, h equation, non-random twoliquid (NRTL) equation and Wilson equation, were applied to correlate the measured solubility data. The correlation results were evaluated by the relative average deviation (RAD). The results indicated that the mole fraction solubility increased with the rising of temperature in all fifteen solvents and all the four correlation models could give a satisfactory result. The experimental data and correlation models would be useful in the purification and synthesis process of 2-aminobenzamide.
