Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Qualifier:

- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- ca. 302 - ca. 304 °C
- Atm. press.:
- 1 Bar
- Decomposition:
- yes
- Decomp. temp.:
- >= 302 - <= 304 °C
- Conclusions:
- The test item had a boiling range at atmospheric pressure of 302 °C to 304 °C. It boiled under decomposition.
- Executive summary:
The purpose of this study was the determination of the boiling point of the test item according to the following guidelines:
European Commission Regulation (EC) No. 440/2008, A.2. Boiling point / boiling range OECD test guideline, OECD 103 (1995) Boiling point/ boiling range and US EPA Product Properties Test Guideline OCSPP 830.7220.
The boiling point / boiling range is determined by differential scanning calorimetry (DSC). The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate (10 K/min) in a defined atmosphere (nitrogen). Crucibles with a small hole are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded.
The mass loss after the DSC measurements amounted to 100 %. After the DSC measurements the aluminium crucibles showed few black residues. Due to this it can be concluded that the test item boiled under decomposition.
The test item had a boiling range at atmospheric pressure of 302 °C to 304 °C. It boiled under decomposition.
