Appearance: white, waxy solid - Key result
- Boiling pt.:
- ca. 227 °C
- Atm. press.:
- 1 007 mBar
- Decomposition:
- yes
- Decomp. temp.:
- 227 °C
- Remarks on result:
- other: From 227°C the test substance showed a boiling and/or thermal decomposition with evaporation of the decomposition components
- Conclusions:
- Under the study conditions, the boiling and/or thermal decomposition of the test substance was earliest at ca. 227°C (at 1007 mbar).
- Executive summary:
A study was conducted to determine the boiling point of the test substance according to OECD Guideline 103 similar to EU Method A.2. To determine the boiling behaviour (four independent single measurements), the test substance was measured by Differential Scanning Calorimetry (DSC) between -90°C and 500°C with a heating rate of 10 K/min. For the measurement; a partially capsulated crucible - typical for boiling point measurements - was used. Under the study conditions, the boiling and/or thermal decomposition of the test substance was determined to be earliest at ca. 227°C (at 1007 mbar) (Kintrup, 2015).
Reference
- Determination following four independent single measurements:
226°C (from first measurement)
227°C (from second measurement)
225°C (from third measurement)
228°C (from fourth measurement)
- From 227°C the test substance showed a boiling and/or thermal decomposition with evaporation of the decomposition components. The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions. The start of the area of boiling temperatures was defined by using the on-set temperature.
Description of key information
The boiling point was determined according to OECD Guideline 103 similar to EU Method A.2 (DSC) (Kintrup, 2015)
Key value for chemical safety assessment
Additional information
227°C at 100700 Pa (boiling and/or decomposition temperature)
