Correct derivation of a combined version of the Jouyban-Acree and van't Hoff model and some comments on 'Determination and correlation of the solubility of myricetin in ethanol and water mixtures from 288.15 to 323.15 K'
چکیده
The experimental data reported in the paper by Cai and co-workers [DOI: 10.1080/00319104.2016.1163560] pertaining to the solubility of myricetin dissolved in binary aqueous-ethanol solvent mixtures has been reanalysed. A correct mathematical derivation is provided for the correlation expression from a combination of the van't Hoff and Jouyban-Acree models. Cai et al. who used the expression in their study, however, erroneously implied that the expression resulted from a simple transformation of the Jouyban-Acree model. No mention was made that one needed to assume a van't Hoff-type mathematical representation for how the solute solubility varied with temperature in the two mixture co-solvents.
