The solubility of Irganox 1010 in (methanol + water), (ethanol + water), and (2-propanol + water) mixed solvents was determined in the temperature range from (293.15 to 333.15) K by a static analytical method. The concentrations of the investigated Irganox 1010 in saturated solution were analyzed by UV spectrometry. A semiempirical equation was proposed to correlate the experimental data. The apparent molar enthalpies of Irganox 1010 in the three systems were determined from the temperature dependence of the solubilities.
