Description of key information
Under the conditions of the study, the boiling point could not be determined, however a consistent exotherm was observed to start at 352 °C indicative of decomposition.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 352 °C
Additional information
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103 under GLP conditions. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
The boiling point of the test material was determined through differential scanning calorimetry.Aliquots of the test material (7.23, 6.26 and 6.23 mg) were weighed into 40 µL aluminium crucibles and a lid with a 50 µm diameter orifice cold welded on to them. Each crucible was subjected to the same heating regime, with an air flow of 50 mL/min. The test material is a liquid at room temperature, so the test was started at -60 °C, isothermal for 15 minutes, then heating at 5 °C/min to 20 °C and then 10 °C/min to 400 °C. Between about 200 °C and about 350 °C small exothermic shifts or small exothermic artefacts were observed, indicating instability, but not quantifiable. A consistent exotherm was observed to start at 352 °C (mean of 356, 349 and 350 °C tests 1-3 respectively) indicative of decomposition. During testing there was an oily burning odour noted suggesting decomposition was occurring. After testing the test crucibles were coated with black residue on the outside and there was a black oily residue inside the crucibles.
Under the conditions of the study, the boiling point could not be determined, however a consistent exotherm was observed to start at 352 °C indicative of decomposition.
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).
