Reference
Description of key information
Henry's Law Constant = 0.1 Pa x m3/mol.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.1
- at the temperature of:
- 25 °C
Additional information
Henry's Law Constant was calculated with HENRYWIN using a water solubility of 382 g/L, a vapour pressure of 100 Pa at 25°C and a molecular weight of 118.17. Henry's Law Constant for the volatility water - air was calculated as 0.1 Pa x m3/mol.
