By formula: C2H5NaO (cr) + 0.5(H2O4S bullet 1100H2O) (solution) = C2H6O (solution) + 0.5Na2O4S (solution)

Quantity Value Units Method Reference Comment
Deltar-28.30 ± 0.91kcal/molRSCBlanchard, Joly, et al., 1974solvent: Sulphuric acid aqueous solution; The reaction enthalpy relies on -2.53 kcal/mol for the enthalpy of solution of EtOH(l) and on 9.97±0.04 for the enthalpy of solution of Na2SO4(cr) Blanchard, Joly, et al., 1974. A value of -117.3 ± 1.4 kcal/mol was derived in Blanchard, Joly, et al., 1974 for the enthalpy of formation. However, this value is affected by a calculation error. Also, the authors have not accounted for the acid dilution (this correction could not be made in the present database, due to lack of information). These problems were also noted in the data compilations Tel'noi and Rabinovich, 1980 and Wagman, Evans W.H., et al., 1982, where the values quoted for the enthalpy of formation, which rely on the experimental data reported in Blanchard, Joly, et al., 1974, are -98.0 ± 1.0 kcal/mol and -98.90 kcal/mol, respectively.
