Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- H:
- 0.13 Pa m³/mol
- Conclusions:
- Henry's Law constant was determined to be 0.13 Pa m3/mol.
Reference
HENRY = (VP x MOLW) / SOL
= (340 x 129.2) / 350000
= 0.13 Pa m3/mol
where:
VP (vapour pressure) = 340 Pa
MOLW (molecular weight) = 129.2 g/mol
SOL (water solubility) = 350000 mg/L
Description of key information
No study was submitted for this endpoint. The value was determined using the algorithms presented in ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R16.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.13
Additional information
Henry's Law Constant was derived using the following calculations:
HENRY = (VP x MOLW) / SOL
= (340 x 129.2) / 350000
= 0.13 Pa m3/mol
where:
VP (vapour pressure) = 340 Pa
MOLW (molecular weight) = 129.2 g/mol
SOL (water solubility) = 350000 mg/L
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
