Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- August 29, 2003 - September 12, 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- (1992)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- (using ASTM E537-86)
- Key result
- Atm. press.:
- >= 102.3 - <= 102.65 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 304 °C
- Remarks on result:
- other: Decomp. temp: 577 K (mean of 2 measurements)
- Conclusions:
- The substance has no boiling temperature. Using differential scanning calorimetry up to 400°C boiling of the test substance was not observed. Decomposition of the substance started at 304°C (GLP-compliant study in accordance with EC A.2).
Reference
- First experiment: Starting from 301.3°C (574 K) an exothermic effect was observed. After the experiment there was a black/brown residue present.
- Second experiment: Starting from 307.1°C (580 K) an exothermic effect was observed. After the experiment there was a black/brown residue present.
- The results were interpreted as: gradual decomposition.
Description of key information
The substance has no boiling temperature. Decomposition of the substance started at 304°C.
Key value for chemical safety assessment
Additional information
Using differential scanning calorimetry up to 400°C in a GLP-compliant study in accordance with EC A.2, boiling of the test substance was not observed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
