- Version / remarks:
- 1996
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- > 400 °C
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- no
- Conclusions:
- Under the conditions of this study the boiling point of the test material was not below 400 °C.
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103, EU Method A.2 and OPPTS 830.7220, under GLP conditions.
A preliminary test was performed using a thermogravimetric analyser (TGA) as a safety precaution for the DSC (differential scanning calorimeter) main test.
No effects were observed which were due to boiling of the test material in the preliminary or main test. After the experiment, the sample appeared unchanged, i.e. no decomposition and/or evaporation were observed.
The standard boiling temperature is defined as the temperature at which the vapour pressure of a liquid is the same as the standard pressure (i.e. 1013.25 hPa).
Under the conditions of this study the boiling point of the test material was not below 400 °C.
Reference
Preliminary Test
- No weight loss was observed during the experiment.
- After the experiment, the sample appeared to have been unchanged, i.e. no signs of decomposition and/or evaporation were observed.
Main Study
- No effects were observed which were due to boiling of the test material.
- After the experiment, the sample appeared unchanged, i.e. no decomposition and/or evaporation were observed.
Conclusion
- Boiling of the test material was not observed below 400 °C (> 673 K).
Description of key information

Key value for chemical safety assessment
Additional information
The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103, EU Method A.2 and OPPTS 830.7220, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
A preliminary test was performed using a thermogravimetric analyser (TGA) as a safety precaution for the DSC (differential scanning calorimeter) main test.
No effects were observed which were due to boiling of the test material in the preliminary or main test. After the experiment, the sample appeared unchanged, i.e. no decomposition and/or evaporation were observed.
The standard boiling temperature is defined as the temperature at which the vapour pressure of a liquid is the same as the standard pressure (i.e. 1013.25 hPa).
Under the conditions of this study the boiling point of the test material was not below 400 °C.
