Physical Properties

Cheméo can also estimate Normal Boiling Point Temperature, Normal melting (fusion) point, Critical Temperature, Critical Pressure, Critical Volume, Enthalpy of formation at standard conditions, Enthalpy of vaporization at standard conditions, Standard Gibbs free energy of formation, Acentric Factor, Ionization energy, Log10 of Water solubility in mol/l for this compound, but they fall outside the models' validated range, so they are not shown here. Open the prediction tool to compute them on demand.
