Several errors in the published paper by Wongkaew and coworkers [Fluid Phase Equilibria 434 (2017) 141-151] are identified. The errors noted include the failure of the calculated curve-fit parameters for the Modified Apelblat model, the van't Hoff model and the empirical polynomial equation in temperature to correctly back-calculate the measured solubility data for the salts of 2-mercaptobenzothiazole with cyclohexylamine (2-MBT-CHA) and tert-butylamine (2-MBT-TBA) dissolved in methyl isobutyl ketone (MIBK), 1,4-dioxane, toluene and water in the temperature range from 303.15 K to 348.15 K. Internal inconsistencies were noted in the reported thermodynamic properties of dissolution, and several errors were noted in the experimental mole fraction solubilities versus temperature graphs.
