Errors are discovered regarding the published equation coefficients of Fan and co-workers [J. Chem. Thermodynamics 58 (2013) 288-291] for mathematically describing the solubility behavior of evodiamine in neat solvents using the modified Apelblat equation. The back-calculated values using the published equation coefficients are not the mole fraction solubility as stated in the published paper. What's more, the parameters in the modified Apelblat equation were re-analysed according to the experimental solubility data. (C) 2018 Elsevier Ltd.
