- Specific details on test material used for the study:
- Batch No.: 465884
Purity: 100% - Atm. press.:
- 1 013.25 hPa
- Decomposition:
- yes
- Decomp. temp.:
- > 200 °C
- Conclusions:
- Reaction and/or decomposition of the test item was observed during DSC experiments starting at 200℃ (473K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
- Executive summary:
The boiling temperature of test item were determined by DSC according to OECD 103.
Reaction and/or decomposition of the test item was observed during DSC experiments starting at 200℃ (473K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
Reference
An endothermic effect was observed between 100℃ and 150℃ followed by an endothermic and exothermic effect starting at 200℃. The extrapolated onset temperature of the first endothermic effect was 125.542℃. The endothermic effect was most likely obtained due to melting of the test item. The second endothermic and exothermic effect were due to reaction and/or decomposition of the test item.
After the experiment, a red/brown molten residue remained in the sample container (original colour: white to off-white to slightly yellow). Based on this visual observation, it was found that the test item had molten and the change of the colour demonstrated reaction and/or decomposition of the test item.
Description of key information
The boiling temperature of test item were determined by DSC according to OECD 103.
Reaction and/or decomposition of the test item was observed during DSC experiments starting at 200℃ (473K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
