The preliminary measurement in a closed glass pan shows an endothermic effect (melting) in the range 110 -155 °C, with an onset of 136.6 °C.

In aluminium pans, the diagrams show the endothermal effect (melting) in the range between 110 and 150 °C, with a medium onset of 135.5 °C and a second endothermal effect (boiling) is in the range between 265 and 345 °C with a medium onset of 341 °C, directly followed by an exothermal effect beginning at about 345 °C.

The test item has a mean boiling point of 341 °C.

Conclusions:
The test item has a mean boiling point of 341 °C..
Executive summary:

The determination of the boiling point was carried out by differential scanning calorimetry (DSC) according to EG-Guideline 92/69/EEC A.2.

The test substance shows a boiling point in the temperature range 341 -343 °C with an onset of 341 °C followed by an exothermal decomposition beginning at about 345 °C.

Description of key information

The determination of the boiling point was carried out by differential scanning calorimetry (DSC) according to EG-Guideline 92/69/EEC A.2.

The test substance shows a boiling point in the temperature range 341 -343 °C with an onset of 341 °C followed by an exothermal decomposition beginning at about 345 °C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
341 °C

Additional information

No atm. pressure is mentioned in the report, but 1013 hPa as standard conditions can be assumed. This does not affect the chemical safety assessment.
