Mistakes are discovered for the published model coefficients of Chen and co-workers [J. Chem. Thermodynamics 95 (2016) 99-104] for mathematically describing the solubility of 2,2',4,4',6,6'-hexanitrostilbene in binary solvent mixture of {DMF (1) + acetonitrile (2)} using the Jouyban-Acree model. The calculated values using the published model coefficients for this model are not the mole fraction solubility as stated in the published paper except for the composition x(C) = 0. Large differences are found between them. The model coefficients are re-analysed by using the Jouyban-Acree model according to the authors' experimental solubility data. (C) 2018 Elsevier Ltd.
