Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point
Administrative data
- Endpoint:
- boiling point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid which melts above 300°C
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The melting point of the substance was found to be above 600 °C in a DSC analysis and above 1000 °C in a DTA in nitrogen atmosphere. The substance undergoes oxidative decomposition in an air atmosphere at 840 °C. Therefore, measurement of a boiling point under reduced pressure is not necessary.
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 12 Jun 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Remarks:
- and Differential Thermo-Analysis (DTA)
- Melting / freezing pt.:
- > 600 °C
- Decomposition:
- yes
- Decomp. temp.:
- 840 °C
- Remarks on result:
- other: No melting point in the temperature range 22 - 600 °C; Oxidative decomposition in an air atmosphere at 840 °C.
- Conclusions:
- No melting point observed in the temperature range 22-600 °C. The substance undergoes oxidative decomposition in an air atmosphere at 840 °C.
Results
DSC: Neither Tg (glass transition temperature) nor melting point was observed between 22 to 600 °C.
DTA: Neither endothermic nor exothermic peak was observed between 20 to 1000 °C in a nitrogen atmosphere. The peak due to oxidative decomposition was observed at 840 °C in an air atmosphere.
Conclusion
The test item has no melting point in the temperature range of 22 - 600 °C. Oxidative decomposition of the test item was occurred at 840 °C.

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.
