Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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)
Adequacy of study:
other information
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Scientifically accepted method
H:
0 Pa m³/mol
Temp.:
20 °C
Remarks on result:
other: Calculated based on vapor pressure, water solubility and molecular weight.

The Henry's Law Constant is calculated based on vapor pressure, water solubility and molecular weight:

Vp = 5.34 * 10^-4 Pa at 20°C

Sw = 513.1 g/L at 20°C

MW = 498.2 g/mol

H = Vp x Sw / MW = 5.18E-07 Pa x m³/mol

Description of key information

Calculation based on physico-chemical properties.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0
at the temperature of:
20 °C

Additional information

The Henry's Law Constant is calculated based on vapor pressure, water solubility and molecular weight and was determined to be 0.000000518 Pa x m³/mol at 20°C.
