Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- other: Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC)
- Decomposition:
- yes
- Remarks on result:
- other: No definite boiling point could be detected up to the decomposition.
- Conclusions:
- Up to the decomposition of the test item no definite boiling point was observed. No pressure was reported.
- Executive summary:
The sample was weighed in a crucible made of aluminium, cooled down in a DTA/DSC-system to 20 °C and then heated up to 450 °C (heating rate 5 K/min). In comparison with an inert sample (empty crucible) the temperature difference and the heat effect was recorded. Any thermal effect corresponds to a baseline deviation. Up to the decomposition of the test item no definite boiling point was observed. This procedure conforms to test method A.1. (section 1.4.4), "Determination of the melting point", described in the EC-Guideline.

Description of key information
No definite boiling point could be detected up to the decomposition.
Key value for chemical safety assessment
Additional information
Between 380 and 450 °C an additional endothermic phase was visible. Additionally a decomposition of the test item seemed to take place. This assumption is supported by the observation that the substance seems to change chemically since a beige-brownish melted mass could be found in the crucible after the heat process.
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.
