Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
Henry's law constant
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Principles of method if other than guideline:
HenryWin (v3.20): HENRYWIN estimates the Henry's Law Constant of organic compounds at 25 °C using the methodology originally described by Hine and Mookerjee (1975).
Key result
H:
2.65 Pa m³/mol
Temp.:
25 °C
Conclusions:
The Henry's law constant was calculated to be 2.65 Pa m3/mol (calculated by HENRYWIN v3.20). Thus, it can be assumed that the susbtance will not evaporate into the atmosphere from the water surface.
Executive summary:

The Henry's law constant was calculated to be 2.65 Pa m3/mol (calculated by HENRYWIN v3.20).

The calculation is based on the following input parameters (please refer to IUCLID section 4):

- water solubility: 742 mg/L

- vapour pressure: 12 Pa.

Description of key information

The Henry's law constant was calculated to be 2.65 Pa m3/mol (calculated by HENRYWIN v3.20). Thus, it can be assumed that the susbtance will not evaporate into the atmosphere from the water surface.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
2.65
at the temperature of:
25 °C

Additional information

The Henry's law constant was calculated to be 2.65 Pa m3/mol (calculated by HENRYWIN v3.20).

The calculation is based on the following input parameters (please refer to IUCLID section 4):

- water solubility: 742 mg/L, at 20°C

- vapour pressure: 12 Pa, at 25°C
