Further computations on the solubility of 2-methyl-1,3-benzothiazol-5-amine in ethanol + water mixtures at several temperatures

ABSTRACT

The recently reported solubility data of 2-methyl-1,3-benzothiazol-5-amine in the binary mixtures of {ethanol (1) + water (2)} at various temperatures have been used to present further numerical calculations and thermodynamic analysis. In this regard, the Jouyban-Acree, combined nearly ideal binary solvent/Redlich–Kister (CNIBS/R-K), Jouyban-Acree–van’t Hoff, Yalkowsky and modified Wilson models were used to correlate the solubility data. In addition, the prediction based on the minimum number of experimental data were examined by Jouyban-Acree–van’t Hoff and extended Yalkowsky models as well as trained version of Jouyban-Acree model presented in our previous research. Finally, the thermodynamic functions, apparent Gibbs free energy, enthalpy and entropy of the dissolution were calculated based on the van’t Hoff equation.
