ABSTRACT
In an equilibrium vessel, the solubility of antioxidant 1010 in pure alkanolswas measured in the temperature range from283.15K to 343.15K using amethod in which an excess amount of solutewas equilibrated with the alkanol solution. The liquid concentrations of the investigated antioxidant 1010 in the saturated solution were analyzed by UV-spectrometry. The solubility data have been correlated as functions of the temperature. Activity coefficients for antioxidant 1010 have been calculated by means of the Wilson, NRTL and UNIQUAC equations and with themwere correlated solubility data thatwere compared with the experimental ones. The best correlation of the solubility data has been obtained by the Wilson equation, by which the average root-mean-square deviation of temperature for the seven systems is 0.62 K.
