Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential thermal analysis
- Decomposition:
- yes
- Remarks on result:
- other: No definite boiling point could be detected up to the decomposition.
- Conclusions:
- No definite boiling point could be detected up to the decomposition of the substance. The alleged boiling range was 320-350 °C.
- Executive summary:
A differential thermoanalysis method (DTA) was used to determine the boiling point which conforms with the procedure Test method A.2, "Determination of the boiling point", described in the EC-Guideline. A boiling range of the test item between approx. 320 to 450 °C could be observed. After the boiling process the test item seems to be chemically changed. This is supported by the orange colouring of the test item residue in the crucible.

Description of key information
No definite boiling point could be detected up to the decomposition of the substance. The alleged boiling range was 320-350 °C.
Key value for chemical safety assessment
Additional information
A boiling range of the substance between approx. 320 to 450 °C could be observed. After the boiling process the test item seems to be chemically changed. This is supported by the orange colouring of the test item residue in the crucible. Between 80-160 °C an endothermic phase could be detected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
