Endpoint:
Henry's law constant
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Study period:
Calculated 2012-04-23
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Accepted calculation method
Principles of method if other than guideline:
Calculation: Vapour pressure x molecular weight / water solubility = 0.02 Pa x 172.32 g/mol / (5900 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 0.00058 Pa m³/mol at 20 °C indicates low volatility of decamethylenediamine from surface waters.
Executive summary:

The calculated Henry’s Law constant of 0.00058 Pa m³/mol at 20 °C indicates low volatility of decamethylenediamine from surface waters.
