Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1983
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- yes
- Remarks:
- - using the thermobalance method instead of the gas saturaiton in the lowest vapour pressure range
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Remarks:
- Thermogravimetry (TGA)
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Remarks on result:
- other: extrapolated
- Conclusions:
- The vapour pressure of test substance was extrapolated to be 0.0002 Pa at 25°C
Reference
TA (11Pa): 131°C
Heat of evaporation: 87.7kJ/mol
Heat of fusion (DSC): 25.8 kJ/mol
Heat of sublimation: 113.5 kJ/mol
Melting point (DSC): 74.8°C
Description of key information
The study provided was conducted to recognised testing guidelines and with GLP certification.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure was measured by thermogravimetry (diffusion controlled evaporation)
