- Executive summary:
Henrys LC [via VP/WSol estimate]:
HLC: 1.316E-009 atm-m3/mole (1.333E-004 Pa-m3/mole)

Reference
Description of key information
Henry's constant has been estimated on 1.32E-4 Pa m3/mol. This value concludes that volatilization of pentaerythritol pentanitrate from moist soil surfaces/ water surfaces is not expected to be an important fate process.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 25 °C
Additional information
The Henry's Law constant for pentaerythritol tetranitrate was estimated from its vapor pressure (1.36E-7 mm Hg), and water solubility (43 mg/L).
