Results and discussion
Vapour pressure
- Temp.:
- 20 °C
- Vapour pressure:
- 0.001 hPa
- Remarks on result:
- other: extrapolated value
Vapour pressure at 50°C (if relevant for classification of gas under pressure)
- Vapour pressure:
- 0.033 hPa
- Remarks on result:
- other: extrapolated value
Any other information on results incl. tables
The measurement were done from 0,99 hPa (92 °C ) to 1000.01 hPa (269.98 °C)
The vapour pressures at 20 °C and 50 °C are extrapolated with help of the antoine equation:
ln (p/bar) = 9.4239 -3967.69 / (150.81 + T in °C)

Applicant's summary and conclusion
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.
