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 = 5.35 was used for the temperature of 280-290°C.

The lowest measured onset temperature is corrected to the standard pressure to be 275.79°C and the highest onset temperature to be 277.43°C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 276.61°C, the test item has a boiling range of 276-277°C.

Conclusions:
The test item was found to have a boiling range of 276 – 277°C.
Executive summary:

The boiling point of the test item was assessed according to OECD 103, differential scanning calorimetry.

An endothermic effect was observed in the range 90 to 300°C which was assigned to boiling of the substance.

The lowest measured onset temperature is corrected to the standard pressure to be 275.79°C and the highest onset temperature to be 277.43°C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 276.61°C, the test item has a boiling range of 276-277°C.

Description of key information

The boiling range was experimentally determined to be 276 -277°C at atmospheric pressure (1013 hPa).

Key value for chemical safety assessment
