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:
- 15 January 2016 to 07 December 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 173 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 173 - <= 400 °C
- Remarks on result:
- other: Atmospheric pressure not reported.
- Conclusions:
- Under the conditions of this study the onset of boiling was at 173 °C (mean of 171.4 and 173.8 °C) with decomposition.
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103, under GLP conditions.
The experiment was performed using a differential scanning calorimeter, the test material was a liquid so the test was started at - 60 °C held isothermally for 15 minutes, then heated at 5 °C/min to 20 °C and then 10 °C/min to 400 °C. Two determinations using 5.47 and 6.41 mg were made.
Two endotherms were observed, the second one closely following the first and ending exothermically, the reaction was still in progress at 400 °C, and a red-brown stain remained in the crucible at the end of the test. This would suggest boiling over a broad range with decomposition.
Under the conditions of this study the onset of boiling was at 173 °C (mean of 171.4 and 173.8 °C) with decomposition.

Additional information
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
