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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Several independant sources indicate that the vapour pressure is 3905 kPa at 25°C and 4080 kPa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 3 905 kPa
- at the temperature of:
- 25 °C
Additional information
- 4080 kPa at 20°C (source: INRS)
- 3295 kPa at 22°C(source: Biocidal assessment report of aluminium phosphide)
- 3905 kPa at at 25°C(source: HSDB on the base of Daubert)
Differents reliable sources indicate the following results for phosphine :
Nota: Vapour pressure testing is also not required for chemicals with a standard boiling point of < 30°C as these substances will have vapour pressures above the limit of measurement (i.e. 105Pa), which is the case of phosphine
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
