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 without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- other: EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- no
- Type of method:
- differential thermal analysis
- Remarks:
- Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC)
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 280 - <= 450 °C
- Remarks on result:
- other: Up to the decomposition of the test item no definite boiling point was observed
- Conclusions:
- Up to the decomposition of the substance no definite boiling point was observed.
- Executive summary:
A differential thermoanalysis method (DTA) was used to determine the melting point which conforms with the procedure test method A.1, "Determination of the melting point", described in the EC-Guideline. Up to the decomposition of the test item no definite boiling point was observed. The melting process was found not to be reversible. After cooling down a one-time melted sample the melting point could not be reproduced.

RESULT:
Between 280 °C and 450 °C several endothermic phases could be detected. Up to the decomposition of the test substance no boiling point was observed.
Description of key information
Up to the decomposition of the substance no definite boiling point was observed.
Key value for chemical safety assessment
Additional information
After the melting of the substance an exothermal phase could be observed between 240 and 380 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
