ABSTRACT

Solubility data of benzotriazole (BTA) in fourteen solvents were measured by a static gravimetric method from 268.15K to 303.15K. The results illustrated that the solubility of BTA in N,N-dimethylacetamide is the highest while that in 1,2-dichloroethane is the lowest in all the tested solvents. And the values of solubility increase with the increasing of temperature. Additionally, the modified Apelblat equation, the h equation, the NRTL model and the Wilson model were employed to correlate the experimental solubility data. It was found that all the selected thermodynamic models could give satisfactory correlation results. Furthermore, the thermodynamic properties of BTA during the dissolving process, including the
