Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Calculation based on a measured water solubility value and vapour pressure
Principles of method if other than guideline:
Calculated from the measured water solubility and vapour pressure
GLP compliance:
no
H:
0 - 0.001 Pa m³/mol
Temp.:
25 °C
Executive summary:

Henry's law constant was calculated to be 8.7E-04Pa.m3/mol at 25 °C based on experimental water solubility vapour pressures. This value indicates a low rate of volatilisation from surface water is expected.

Description of key information
