In this work new data were provided for the solubility of gallic acid in (water + ethanol) mixed solvents at temperature range from (293.15 to 318.15) K). The values of the solubility of gallic acid in binary mixed solvents increase with rising temperatures. Two equations were used to correlate the experimental values for the gallic acid solubility. One is a nonlinear equation for the pure solvents while the other is a fifth polynomial equation for the mixed solvents. Calculated solubility values show good agreement with experimental values. Data presented in this work are
essential for the industrial development of gallic acid extraction and purification processes.
