Reference
Endpoint:
Henry's law constant
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Acceptable calculation method using measured physical chemical properties
Principles of method if other than guideline:
Calculated using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16. Measured input values were vapour pressure (560 Pa) and solubility (1900 mg/L).
GLP compliance:
no
H:
48.63 Pa m³/mol
Remarks on result:
other: Calculated using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16.
Conclusions:
The Henry's Law Constant is 48.63 Pa m³/mol. Calculated using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16.
