Any other information on results incl. tables
At temperature above 135 °C a thermal transformation of the test item is suggested due to too high vapour pressures. A re-measurement at lower pressure values shows a increase of the vapour pressure of about 10 %. The value at 140 °C (p = 300 hPa) is not included in the regression equation.
ln (p/Pa) = 103.61555-9483.6277/T-11.97866*lnT+9.54268E-06*T**2

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.
