During the heating phase the test item showed an endothermic signal in the temperature range of approx. 150 – 230 °C that can be associated with the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 3 (e.g. Esters). A correction value φ = 5.2 was used for the temperature of 200 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 197.84 °C and the highest onset temperature to be 197.88 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 197.86 °C, the test item has a boiling point of 198 °C.
No further thermal effects were observed up to the maximum test temperature of 500 °C.
Final Results
The test item has a boiling point of 198 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Description of key information
Boiling point: 198 °C at 1013 hPa (EU Method A.2., differential scanning calorimetry)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 198 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
