The regression of the vapor pressure data leads with a mean deviation of 0.4 % to the following rounded equation:
In ( p/hPa) =16.9862 - 4044.33 / ( 194.35 + t/°C)
The normal boiling temperature was obtained by extrapolation from the vapour pressure curve.
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.
