Results
In the thermograms of the DSC runs (nos. PN9485 and PN9486) no thermal effects were observed in the temperature range from -100 °C to 25 °C. Between approx. 60 and 240 °C an endothermic effect (boiling) could be detected.

During the heating phase the test item showed an endothermic signal in the temperature range of approx. 60 – 240 °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. Acetaldehyde). A correction value φ = 5.2 was used for the temperature of 210 – 220 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 217.63 °C and the highest onset temperature to be 218.43 °C. As the corrected onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 218.03 °C, the test item has a boiling point of 218.0 °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 218 °C at atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Directive EC40/2008 Method A.2., OECD Test Guideline 103 (1995), EPA OCSPP 830.7220 (1998).
Description of key information
Boiling point: 218 °C at 1013 hPa (EU Method A.2. differential scanning calorimetry)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 218 °C
Additional information
The boiling point has been corrected to normal pressure (1013.25 hPa) using the H.N. Hass and R.F. Newton equation.
