Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- additionally: thermogravimetry
- Decomposition:
- yes
- Decomp. temp.:
- 384 - ca. 430 °C
- Remarks on result:
- other: the substance decomposes already in the melting range
- Conclusions:
- The substance begins to melt at about 359 °C. At 385 °C an endothermic decomposition process sets in and superimposes the melting process. Therefore no boiling point can be assigned to the substance.
The effect at about 116 °C seems to be of minor importance. - 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
- the study does not need to be conducted because the substance is a solid which decomposes before boiling
Referenceopen allclose all
Parallel to the DSC measurement the mass loss was determined with a thermo balance during temperature rising. The residues in the crucibles were visually examined after the DSC and thermogravimetric experiment.
There was a minor endothermic effect at about116 °C accompanied by a mass loss of 0.4 %. Beginning at 358 °C the first of two strong endothermic peaks appeared in the DSC. The first peak (with a maximum at 376 °C) overlapped with the second peak (with a maximum at 385 °C). Only the second peak of the DSC was accompanied by a mass loss, which could be detected by the thermo balance. The mass loss happened in the temperature range from 385 to about 430 °C.
The consistence of the black residues found in the crucibles after the experiment indicated, that a melting process had taken place before.
Description of key information
No boiling point can be assigned to the substance. The substance melts above 300 °C and decomposes before boiling.
Key value for chemical safety assessment
Additional information
The substance begins to melt at about 359 °C. This process is followed by an endothermic decomposition starting at 385 °C. Therefore no boiling point can be assigned to the substance.
