Comments on the “Determination and correlation of the solubility and thermodynamic parameters of 2,3,5,4′-tetrahydroxystilbene-2-O-β-d-glucoside in pure organic solvents”

Errors are discovered in the authors' calculated excess enthalpies based on the Buchowski-Ksiazcyak λh equation. The authors inadvertently subtracted the solute's enthalpy of fusion from the product universal gas constant (in Joules/(mole K)) times Buchowski-Ksiazcyak h parameter, without changing the units of solute's enthalpy of fusion to Joules/mole. As a result all of the 81 excess enthalpies given in Table 8 of the published paper by Huang and coworkers are in error.
