The regression of the vapor pressure data leads with a mean deviation of 0.96 % to the following rounded equation:
In ( p/hPa) = 21.2438 -5395.89 / ( 273.15 + t/°C)
With this equation, the values of the following table were calculated:

a) calculated by use of the unrounded regression equation.
b) values not used for regression
c) interpolated
d) extrapolated
Remarks
At a temperature of approximately 60°C and above a continuously increasing vapor pressure was observed. This indicates a thermally caused change of the test item.
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.
