Preliminary test
From 250°C upwards the weight of the sample decreased significantly. At 347°C the sample weight had decreased by 25%. After the experiment, black residue was observed on the lid of the sample container and a charred residue remained in the sample container (original colour: yellow to orange). The change of the colour indicated reaction and/or decomposition of the test substance.
Main study
No effects were observed which were due to melting and/or boiling of the test substance. Exothermic effects starting at 225°C were indicating reaction and/or decomposition of the test substance. After the experiment, black residue was observed on the lid of the sample container and a charred residue remained in the sample container (original colour: yellow to orange). The change of the colour indicated reaction and/or decomposition of the test substance.
Applicant's summary and conclusion
- Conclusions:
- Reaction and/or decomposition of the test substance was observed starting at 225°C (498K). Boiling of the test substance was not observed below this temperature. Based on this, the test 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).
