Key result
Atm. press.:
1 013.25 hPa
Decomposition:
yes
Decomp. temp.:
ca. 175 °C

One DSC measurement in aluminium crucibles with a hole showed no endothermal effect after the melting before the exothermal effect was observed. Therefore, it was concluded that the test item had no boiling point under atmospheric conditions up to 175°C (start of exothermal effect).

Conclusions:
The test item decomposes starting at approx.175 °C. Thus, it has no boiling point at atmospheric conditions.
Executive summary:

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. One DSC measurement in aluminium crucibles with a hole showed no endothermal effect after the melting before the exothermal effect was observed. The test item decomposes starting at approx.175 °C. Thus, it has no boiling point at atmospheric conditions.

Description of key information

The test item decomposes starting at approx.175 °C. Thus, it has no boiling point at atmospheric conditions.

Key value for chemical safety assessment

Additional information

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. One DSC measurement in aluminium crucibles with a hole showed no endothermal effect after the melting before the exothermal effect was observed. Therefore, it was concluded that the test item had no boiling point under atmospheric conditions up to 175 °C (start of exothermal effect) (reference 4.3 -1).
