- yes
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 250 °C
- Remarks on result:
- other: Decomposition tempetarture: > 523K
- Conclusions:
- Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this it can be concluded the test item has no boiling temperature.
- Executive summary:
In a differential scanning calorimetry study, the substance has no boiling temperature. It decomposes at > 250°C. The study was performed in accordance with EC A.2, OECD 103 and EPA OPPTS 830.7220 guidelines and according to the principles of GLP.
Reference
Preliminary TGA
From 325°C upwards the weight of the sample decreased significantly. At 365°C, the sample weight had decreased by 25%. After the experiment, a brown residue remained in the sample container.
DSC Experiment
An exothermic effect was observed starting at 250°C. The testitem changed from an originally colourless to light yellow vicous liquid to a brown molten residue aftet the test. These changes indicate reaction and/or decomposition of the test item.
Boiling of the test substance was not observed below the temperature at which decomposition started.
Description of key information
In a differential scanning calorimetry study, the substance has no boiling temperature. It decomposes at > 250°C.
Key value for chemical safety assessment
Additional information
The study was performed in accordance with EC A.2, OECD 103 and EPA OPPTS 830.7220 guidelines and according to the principles of GLP.
