The test item showed an endothermic signal in the temperature range of 240 – 330 °C, which can be assigned to the boiling of the test item.


The lowest measured onset temperature is corrected to the standard pressure to be 253.4 °C and the highest onset temperature to be 267.2 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 258.3 °C, the test item has a boiling range from 253 °C to 267 °C.

Conclusions:
The boiling range of the test item was determined to be 253 °C to 267 °C.
Executive summary:

An experimental study was conducted to determine the boiling point of the test item according to OECD Guideline 103 and Regulation (EC) No 440/2008, Method A.2 using differential scanning calorimetry. The test item showed an endothermic signal in the temperature range of 240 – 330 °C, which can be assigned to the boiling of the test item. The lowest measured onset temperature is corrected to the standard pressure to be 253.4 °C and the highest onset temperature to be 267.2 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 258.3 °C, the test item has a boiling range from 253 °C to 267 °C.

Description of key information

The boiling range of the test item was determined to be 253 °C to 267 °C (reference 4.3-1).

Key value for chemical safety assessment
