Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
Henry's law constant
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Calculation based on a measured water solubility value for the substance and measured vapour pressure
Qualifier:
no guideline followed
GLP compliance:
no
H:
0 Pa m³/mol
Temp.:
25 °C
Conclusions:
Henry's law constant was calculated to be 6.04E-11 Pa.m3/mol at 25 °C based on experimental water solubility of 36.4 g/L and an experimental vapour pressures for T002102 of 0.00000002 Pa. The value indicates that a low rate of volatilisation from surface water is expected.

Description of key information

Henry's law constant was calculated to be 6.04E-11 Pa.m3/mol at 25 °C based on experimental water solubility and an experimental vapour pressure for T002102. The value indicates that a very low rate of volatilisation from surface water is expected. 

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
