The test item showed a second endothermic signal in the temperature range of approx. 100 – 230 °C that can be assigned to the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 5 (e.g. Benzyl alcohol). According to appendix 8.2 a correction value φ = 5.7 was used for the temperature of 215 °C.
The lowest measured onset temperature was corrected to the standard pressure to be 214.01 °C and the highest onset temperature to be 214.89 °C. As the corrected onset temperatures in both tests deviate less than 0.5 K from their mean value of 214.45 °C, the test item has a boiling point of 214.5 °C.
Description of key information
The boiling point was determined to be 214.5°C by Differential Scanning Calorimetry (DSC).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 214.5 °C
