Executive summary:

Henrys LC [via VP/WSol estimate]:

HLC: 1.316E-009 atm-m3/mole (1.333E-004 Pa-m3/mole)

VP: 1.36E-007 mm Hg

WS: 43 mg/L

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).
