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

atmospheric pressure not specified, but a standard ambient pressure of 1013 hPa can be assumed

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.
