Comments concerning “Solubility and dissolution thermodynamic properties of 1,6-bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamido]hexane in pure solvents and binary solvent mixtures”

Several mathematical errors in the published paper by Zhang and coworkers are identified. The errors pertain to the published equation coefficients for the modified Apelblat and for the polynomial equation based on the Combined Jouyban-Acree and modified Apelblat models. The published curve-fit equation coefficients do not correctly back-calculate the observed solubility data.
