Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20-28 March 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- According to OECD Guideline 103
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- 290 °C
- Atm. press.:
- 973 hPa
- Decomposition:
- no
- Conclusions:
- The boiling point of the test item is 290 ± 5 °C at 1001 hPa.
- Executive summary:
The boiling point of the test substance was determined according to the OECD Guideline 103 using differential scanning calorimetry. At 973 hPa, the boiling point is 290 +/- 5 °C.
Reference
There is an endothermic boiling peak in the 290 to 318 °C region with a mean onset at 290 °C. This peak is followed by an exothermic peak indicating that decomposition starts at a temperature close to the boiling point. The two measurements gave the following values:
Measurement |
Onset (°C) |
Peak (°C) |
Atmospheric pressure (hPa) |
#1 |
290.4 |
296.8 |
973 |
#2 |
290.6 |
299.9 |
973 |
The mean onset (rounded to 290 °C) is selected as giving the best value of the boiling point. The difference between the lower onset value and the higher peak value is used to estimate the uncertainty.
Description of key information
The boiling point of the test item is 290 ± 5 °C at 1001 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 290 °C
Additional information
The boiling point of the test substance was determined according to the OECD Guideline 103 using differential scanning calorimetry. At 973 hPa, the boiling point is 290 +/- 5 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
