Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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)
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.
