Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1987
- 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
- GLP compliance:
- yes
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- > 170 °C
- Atm. press.:
- 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 174 °C
- Conclusions:
- The boiling point was found to be > 170°C at 101.3 kPa. Above 174°C, the substance starts to decompose.
- Executive summary:
The study was performed 1987 as GLP-test following EU-testing method A.2 and using the Siwoloboff method. The test substance started to decompose at approx. 447 K (174°C). During the heating process up t o 573 K (300°C) the colour of the test substance changed from colourless to brown. The measurements were performed at atmospheric pressure. A separate study conducted by another CRO gave a result of > 300°C. See following supporting study.

- Conclusions:
- Upon heating the compound above 100°C it was found to turn gradually from colourless to deep yellow. Boiling did not occur below 300°C, at which temperature the test was stopped.
- Executive summary:
The study was performed 1987 as GLP-test following EU-testing method A.2 and using the capillary method. Upon heating the compound above 100°C it was found to turn gradually from colourless to deep yellow. Boiling did not occur below 300°C, at which temperature the test was stopped.

Description of key information
The boiling point was measured at two different test laboratories. In both labs, the study was performed under GLP and in accordance with EU-testing method A.1. One study used a lower test substance quality and was therefore identified as supporting study. The key study showed a boiling point > 170°C at 101.3 kPa. Above 174°C, the substance started to decompose.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 170 °C
