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:
- December 10, 2002 - February 7, 2003
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study conducted according to EU Method A.2 and GLP. However, more effort could have been taken to investigate partial decomposition during melting in more detail. Two determinations were performed, but using the same parameters.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- (1992)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E537-86
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- (DSC)
- Atm. press.:
- >= 102.01 - <= 102.23 kPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 337 °C
- Remarks on result:
- other: Reaction and/or decomposition of the test substance was observed starting at a temperature of 337°C (610 K)
- Conclusions:
- The boiling temperature of the substance was determined using DSC, according to EU Method A.2 and GLP. Reaction and/or decomposition of the test substance was observed starting at a temperature of 337°C (610K) and an atmospheric pressure of 102.01 - 102.23 kPa.
Reference
Several endothermic effects were observed:
- At approximately 140°C (minor effect; not further explained)
- At approximately 220°C melting of the substance was observed
- At approximately 260°C (very small)
Result experiment #1: decomposition starting at 337.0°C; residue after the experiment: dark brown stain
Result experiment #2: decomposition starting at 337.5°C; residue after the experiment: dark brown stain
Description of key information
Reaction and/or decomposition of the substance was observed starting at a temperature of 337°C (610K) and an atmospheric pressure of 102.01 - 102.23 kPa..
Key value for chemical safety assessment
Additional information
The boiling temperature of the substance was determined using DSC in accordance with EU Method A.2 and GLP.
