The regression of the results leads with a mean deviation of 0.22 % to the following equation:
In(p/hPa) = 17.9346 - 3937.86 / (239.29 + t/°C)
The vapour pressures at 20°C, 25°C and 50°C were extrapolated or calculated fram the regression equation.
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.
