Comment on “Solution Thermodynamics of Benzotriazole in Different Pure Solvents”

Abstract

Mole fraction solubilities were calculated for benzotriazole dissolved in methanol, 2-propanol, 2-butanol, and acetonitrile at 298.15 K based on the published equation coefficients for the modified Apelblat model. In the case of the three alcohol solvents, the calculated mole fraction solubilities of benzotriazole were found to differ by up to 30% from the backcalculated values that the authors reported in their published paper. A significantly larger difference was found in the case of benzotriazole dissolved in acetonitrile.
