- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 15 to 19 Septembre 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The test substance is adequately characterised. Therefore full validation applies.

- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- GLP compliance programme (inspected on 13-14 October 2014 / signed on 8 April 2015)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- ca. 190.4 °C
- Atm. press.:
- ca. 101 325 Pa
- Decomposition:
- no
- Remarks:
- After cooling down a slightly change of the colour was observed.
- Remarks on result:
- other:
- Remarks:
- Mean ± standard deviation (after correction following Sydney Young) = 190.4 ± 0.3 °C (463.5 ± 0.3 K) at standard pressure (101.325 kPa).
- Conclusions:
- The initial boiling temperature of the test item has been determined to be ca 190.4± 0.3 °C, corrected to standard pressure (101.325 kPa).
- Executive summary:
The initial boiling point of the test item was measured under GLP according to OECD 103 / EU A2 guideline, by Siwoloboff.
The test item was filled into a sample tube. The sample tube was then set into the aluminium block at 176.2 °C (first and second determination). For the increase of the temperature, a temperature gradient of 1 °C /min was maintained. When bubbles rose constantly on the capillary, heating was turned down, and, cooling slowly. The temperature at which the chain of bubbles broke was recorded (with its atmospheric pressure) and is considered as the boiling point.The determination was performed in duplicate.
After cooling down a slightly change of the colour was observed.

As the difference between the two determinations was below 2 K the result can be considered valid and theresult is calculated as mean of the two values of the duplicate determination.
Mean ± standard deviation (after
correction following Sydney Young) = 190.4 ± 0.3 °C (463.5 ± 0.3 K) at
standard pressure (101.325 kPa).
Description of key information
The initial boiling point of the test item has been determined to be ca 190.4 ± 0.3 °C, corrected to standard pressure (101.325 kPa).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 190.4 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
