Further analysis and comments regarding solubility and thermodynamic analysis of 1,6-Hexanediamine in mono-solvents and 1-butanol + cyclohexane mixed solvents at different temperatures

The equation coefficients reported by Li and co-workers measuring the solubility of 1,6-Hexanediamine in binary solvents (1-butanol + cyclohexane) using the Jouyban-Acree equation are found to be wrong. The back-calculated values according to Jouyban-Acree equation published by Li and co-workers are inconsistent with the mole fraction solubility in the reported paper, and there is a big difference between the calculated values and the values reported by the author. The equation coefficients listed in Table 6 calculated by author are in error.
