DSC EXPERIMENT
No effects were obtained which were due to boiling of the test substance. The observed exothermic peaks (from 300°C onwards) were due to reaction and/or decomposition of the test substance based on the shape of the heat flow curve. After the experiment, a brown residue remained in the sample container.
Applicant's summary and conclusion
- Conclusions:
- In a GLP-compliant study in accordance with EC A.2, OECD 103 and EPA OPPTS 830.7220 using differential scanning calorimetry, decomposition of the substance was observed starting at 300°C. It was therefore concluded that the substance has no boiling temperature.
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.
