Key result
Atm. press.:
1 013.3 hPa
Decomposition:
yes
Decomp. temp.:
> 410 °C
Remarks on result:
other: The test item had no boiling point.

No endothermal effect was observed after the melting in the temperature range of 145 - 180 °C up to the final test temperature of 500 °C. At a temperature of approximately 410 °C the starting of an exothermal effect was detected. After the DSC measurement a black residue and a mass loss of 7.7 mg (66 wt.%) were detected. Thus, it was concluded, that the test item decompose before boiling.

Conclusions:
The test item had no boiling point at atmospheric conditions up to 410°C. The test item decomposed starting at 410°C.
Executive summary:

A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 11 – 12 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. The test item and the reference were heated up from the starting temperature to the final temperature of 500 °C at a constant heating rate (10 K/min) in a defined atmosphere (nitrogen). No endothermal effect was observed after the melting in the temperature range of 145 - 180 °C up to the final test temperature of 500 °C. At a temperature of approximately 410 °C the starting of an exothermal effect was detected. After the DSC measurement a black residue and a mass loss of 7.7 mg (66 wt.%) were detected. Thus, it was concluded, that the test item decompose before boiling.

Description of key information

The test item decompose before boiling (reference 4.3 -1).
