Atm. press.:
ca. 1 013.25 hPa
Decomposition:
yes
Decomp. temp.:
> 370 °C
Remarks on result:
not determinable
Remarks:
The test item had no boiling point at atmospheric conditions

The DSC measurements in aluminium crucibles with a hole showed no endothermal effect after melting up to 390 °C. Above 390 °C the baseline became ambiguous. After the measurement a black residue was observed. The mass loss after the DSC measurement amounted to 87 %.

Linder consideration of the result from the DSC measurements and the thermal stability (see 4.14) it was concluded that the test item had no boiling point at atmospheric conditions. Decomposition started at approx. 370 °C.

Conclusions:
The test item had no boiling point at atmospheric conditions. Decomposition started at approx. 370 °C.
Executive summary:

A study was conducted according to OECD test guideline 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded.The test item had no boiling point at atmospheric conditions. Decomposition started at approx. 370 °C.

Description of key information

The test item had no boiling point at atmospheric conditions. Decomposition started at approx. 370 °C.

Key value for chemical safety assessment
