Key result
Boiling pt.:
°C
Atm. press.:
ca. 1 013.25 hPa
Decomposition:
yes
Decomp. temp.:
> 170 °C
Remarks on result:
not determinable
Remarks:
The material had no boiling point under athmospheric condictions.

Two DSC measurements in aluminium crucibles with a hole showed an exothermal effect starting at approximately 170°C. No further endothermal or exothermal effects were observed up to the final temperature (500 "C). The mass loss after the DSC measurements amounted to approx. 57%.

Under consideration of the results from the thermal stability and the DSC measurements it was concluded that the test item had no boiling point under atmospheric conditions. Decomposition started at approx. 170 °C.

Conclusions:
The test item had no boiling point under atmospheric conditions. Decomposition started at approx 170 °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 under atmospheric conditions. Decomposition started at approx. 170 °C.

Description of key information

The test item had no boiling point under atmospheric conditions. Decomposition started at approx. 170 °C.

Key value for chemical safety assessment
