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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: well performed calculation with acknowledged software. The MPBPWIN 1.43 software does not accept structures containing iron. Therefore the vapour pressure from surrogate disodium oxalate was calculated.
- Qualifier:
- according to guideline
- Guideline:
- other: calculation
- Principles of method if other than guideline:
- Calculation of the vapour pressuere with Software / MPBPWIN 1.43 (Syracuse Research Corporation)
- GLP compliance:
- no
- Type of method:
- other: calculation
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The calculated vapour pressure of the disodium oxalate is < 0.000001 Pa at 20°C. Due to the much higher molecular weight the vapour pressure of the submission substance is expected to be lower.
Reference
Taking into account the structure and the molecular weight of trisodium trioxalatoferrate it is clear, that the vapour pressure of the submission substance will have an even lower vapour pressure than the much smaller disodium oxalate.
Description of key information
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
well performed calculation with acknowledged software. The MPBPWIN 1.43 software does not accept structures containing iron. Therefore the vapour pressure from surrogate disodium oxalate was calculated.
The calculated vapour pressure is below the a.m. value.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
