Any other information on results incl. tables
Two measurements were performed with the values: 350 °C and 360 °C, mean: 355 °C.
Two boiling points showed a difference of 10 K, which is not in accordance with the demanded limit of max. 2 K. This is very likely due to a decomposition which is also expected on the basis of DSC-measurements for melting point.
Due to very high boiling temperature the measurement with this method has an average error of ± 5 K. A possible pressure correction (by means of the Sidney Young equation) of ± 1.5 K was not applied as it was much less than the measurement error.
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.
