Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Basic data given.
- Principles of method if other than guideline:
- thermodynamical method
- GLP compliance:
- not specified
- H:
- 0 dimensionless
- Temp.:
- 25 °C
- Conclusions:
- The Henry's Law constant of 0.168 Pa m³/mol at 25°C indicates that the substance is slightly volatile from water.
- Executive summary:
The experimentally determined Henry's Law constant of the substance at 25°C is 0.000068. The value was given as dimensionless Henry's Law constant (K air-water), converted according to the "Guidance Document R16, October 2012, Chapter R.16.5.3.2", the value equates to 0.168 Pa m3 / mol. This value indicates that the substance is slightly volatile from water.
Reference
atmospheric pressure not specified, but a standard ambient pressure of 1013 hPa can be assumed

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).
