The regression of the results leads with a mean deviation of 0.24 % to the following equation:
In(p/hPa) =16.8481 - 3801.78 / (207.86 + t/°C)
The normal boiling temperature was obtained by intrapolation from the vapour pressure curve.
The test item is liquid in the temperature range used for the vapour pressure measurements.
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.
