Comment on “Volumetric and compressibility behavior of l-valine in aqueous poly ethylene glycol solutions at T = (298.15, 308.15 and 318.15) K”

Search of the chemical literature reveals that the limiting apparent molal volumes for l-valine dissolved in water differ significantly from published literature values. The calculated limiting apparent molal volumes reported by Moradian and coworkers [J. Mol. Liq., in press, doi:https://doi.org/10.1016/j.molliq.2018.08.027] were φvo = −145.8768 cm3 mol−1 and φvo = −273.5163 cm3 mol-1 at 308.15 K and 318.15 K, respectively. Published literature values were in the range of about φvo = 90 cm3 mol−1 to φvo = 92 cm3 mol−1.
