The regression of the vapor pressure data leads with a mean deviation of 0.4% to the following equation:
In ( p/hPa) = 18.4310-3566.78 / (213.01 + t/°C)
The normal boiling temperature was determined at 96.9 °C by extrapolation of the data with this equation.
Remarks
The test item showed fluctuating vapor pressure values - appr. ± 0.4 hPa - at any given temperature. However, these fluctuations were negligible in case of the determination of the normal boiling temperature.

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.
