Physical Properties

Cheméo can also estimate Critical Temperature, Critical Pressure, Critical Volume, Standard Gibbs free energy of formation, Acentric Factor, 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.
