Applicant's summary and conclusion
- Conclusions:
- boiling point: 283 degree C.
- Executive summary:
In the second run from room temperature to 400 degree C an endothermic enthalpy change was detected at 285 degree C (peak maximum). The extrapolated onset temperature of the evaporation process was determined to 283 degree C. The mass loss of only 72.2 % can be explained by the simultaneous polymerization which is recognizable in an exotheric enthalpy change with maximum at 308 degree C.
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.
