Administrative data
Link to relevant study record(s)
Description of key information
The Henry's Law constant has been estimated from the ratio of the vapour pressure to the water solubility (Equation R16-11 of the of the guidance on information requirements and chemical safety assessment - chapter R16: environmental exposure assessment (ECHA 2008)) as follows:
HENRY = ( VP x MOLW ) / SOL = 0.000000052 Pa.m3.mol
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
Additional information
The Henry's Law constant has been estimated from the ratio of the vapour pressure to the water solubility (Equation R16-11 of the of the guidance on information requirements and chemical safety assessment - chapter R16: environmental exposure assessment (ECHA 2008)) as follows:
HENRY = ( VP x MOLW ) / SOL = 0.000000052 Pa.m3.mol
with:
VP = Vapour pressure (Pa) = 2.07x10-7
MOLW = Molecular weight (g/mol) = 201.31
SOL = Solubility (mg/L) = 800 mg/L
