The regression of the results leads with a mean deviation of 0.14 % to the following equation:
ln(p/bar) = 9,5697 - 3906,75 / (195,25 + t/°C)
The normal boiling point was calculated from 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.
