Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- 0 atm
- Temp.:
- 20 °C

- Transition / decomposition:
- yes
- Transition temp.:
- >= 220 °C
- Conclusions:
- The vapour pressure calculated for the substance is 0.189 Pa (20 °C)
- Executive summary:
The vapour pressure of the substance was determined according to OECD Guideline 104 (vapour pressure), adopted on 23 March 2006. Isolation of the substance from the commercial product in a degree of purity that would allow the determination of its vapour pressure by experimental means is technically not possible. Therefore the vapour pressure of the substance was determined according to the Estimation Method (modified Watson correlation) described in the Annex to OECD Guideline 104.
The only experimental data required is the normal boiling point. No boiling point could be determined for the substance. Instead decomposition started at 220 °C. This temperature was considered to be the lowest possible boiling temperature. The vapour pressure obtained by calculation is 1.87 x 10E-6 atm (= 0.189 Pa) at 20 °C.

Additional information
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.
