Key result
H:
0.436 Pa m³/mol
Temp.:
20 °C
Conclusions:
The Henry's law constant was calculated to be 0.436 Pa m3/mol. The Henrys law constant is calculated according to ECHA guidance R.16: Environmental exposure assessment (ECHA 2016) using experimental data for water solubility and vapour pressure.
Executive summary:

The Henry's law constant was calculated to be 0.436 Pa m3/mol (ECHA guidance R.16: Environmental exposure assessment (ECHA 2016)).

The calculation is based on the following input parameters (please refer to IUCLID section 4):

- water solubility: 7799 mg/L

- vapour pressure: 25 Pa at 20 °C
