Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- supporting study
- Study period:
- 2010-07-14
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Accepted calculation method; restriction: default required for water solubility due to miscibility
- Principles of method if other than guideline:
- Calculation: Vapour pressure x molecular weight / water solubility = 4 Pa x 158.29 g/mol / (1,000,000 g/m3)
- H:
- 0.001 Pa m³/mol
- Temp.:
- 20 °C
- Atm. press.:
- 1 013.25 hPa
- Conclusions:
- The calculated Henry’s law constant of 0.00063 Pa m3/mol indicates very low volatility of 2,2,4(or 2,4,4)-trimethylhexane-1,6-diamine from surface waters.
- Executive summary:
The calculated Henry’s law constant of 0.00063 Pa m3/mol indicates very low volatility of 2,2,4(or 2,4,4)-trimethylhexane-1,6-diamine from surface waters.
