Reference
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
Principles of method if other than guideline:
Experimental data on vapour pressure and water solubility are available. Therefore, the VP/WS ratio is calculated as estimation method for Henry´s Law constant.
GLP compliance:
no
Key result
H:
2 948.8 Pa m³/mol
Temp.:
25 °C
Conclusions:
The Henry's law constant was calculated to be 2948.8 Pa m3/mol.
Executive summary:

Because experimental data on vapour pressure and water solubility are available the VP/WS ratio is an adequate and reliable estimation method for Henry´s Law constant.

The Henry's law constant was calculated to be 2948.8 Pa m3/mol

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

- water solubility: 17.817 mg/L

- vapour pressure: 380 Pa

Description of key information

The Henry's law constant was calculated to be 2948.8 Pa m3/mol (calculated with VP/WS ratio).

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
2 948.8
at the temperature of:
25 °C

Additional information

The Henry's law constant was calculated to be 2948.8 Pa m3/mol (calculated with VP/WS ratio).

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

- water solubility: 17.817 mg/L

- vapour pressure: 380 Pa (at 25 °C)
