- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 23 to 24 November 2017
- 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.
- Qualifier:
- 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 20-21 June 2017 / signed on 4 September 2017)
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 180 °C
- Remarks on result:
- other: During the heating phase an exothermal effect was observed starting at 180 °C
- Conclusions:
- The test item had no boiling point before decomposition at atmospheric conditions. Decomposition started at approx. 180 °C .
- Executive summary:
The initial boiling point of the test item was measured under GLP according to OECD 103 / EU A2 guideline, by DSC.
Two DSC measurements in aluminium crucibles with a hole with addition of glass pearls were performed. In each case the test item was cooled down to -50 °C with a cooling rate of 1 K/min, kept at -50 °C for 30 min and afterwards the test item was heated up to 500 °C with a heating rate of 10 K/min. During the heating phase an exothermal effect was observed starting at 180 °C, directly followed by an endothermal effect.

Results
Boiling point / boiling range : Differential scanning calorimetry
Two DSC measurements in aluminium crucibles with a hole with addition of glass pearls were performed. In each case the test item was cooled down to -50 °C with a cooling rate of 1 K/min, kept at ‑50 °C for 30 min and afterwards the test item was heated up to 500 °C with a heating rate of 10 K/min. No effect was observed during the cooling phase and keeping the test item at -50 °C. During the heating phase an exothermal effect was observed starting at 180 °C, directly followed by an endothermal effect.
The results of the DSC measurements are summarized in the table below:

Graphical presentations of the DSC runs are shown on page 7 of the experimental report.
Under consideration of the result from the DSC measurement it was concluded that the test item had no boiling point at atmospheric conditions. Decomposition started at approx. 180 °C.
Description of key information
The test item had no boiling point at atmospheric conditions before decomposition. Decomposition started at approx. 180 °C
Key value for chemical safety assessment
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, and the result is retained as key data.
