Solubility of gallic acid in methanol, ethanol, water, and ethyl acetate

The solubility of gallic acid in methanol, ethanol, water, and ethyl acetate was measured at a temperature range of (298.2 to 333.2) K. The gallic acid solubility in different solvents increases smoothly with temperature. The relative solubility of gallic acid in the solvents was found as: w(methanol) > w(ethanol) > w(water) > w(ethyl) (acetate). The temperature dependence of the solubility data was correlated by the modified Apelblat model. The calculated solubilities show good agreement with the experimental data in the temperature range studied.
