- Key result
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- > 300 °C
- Remarks on result:
- not determinable
- Conclusions:
- The test item has no boiling temperature; it decomposes at temperatures > 300ºC.
- Executive summary:
The study to determine the boiling point of the test item was performed according to OECD 103 / EU Method A.2, under GLP conditions. A preliminary study was conducted using a thermogravimetric analyser (TGA). Based on the results, a differential scanning calorimetry study (DSC) was performed to determine the boiling point of the test item. Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of > 300°C (> 573K). Melting and/or 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
- Preliminary test: Starting at 350°C, the weight of the sample decreased significantly. At 549°C, the sample weight had decreased by 23%. After the experiment, a white residue remained in the sample container (original colour: white to off-white). The change of the colour indicated reaction and/or decomposition of the test item.
- Main study: An endothermic peak was observed between 25°C and 175°C. Based on the weight loss observed during the preliminary test, the endothermic effect was due to evaporation of volatile components. An endothermic peak was observed starting at 300°C. The endothermic effect was due to reaction and/or decomposition of the test item. After the experiment, a white to off-white residue remained in the sample container.
Description of key information
Key study. Method according to OECD 103 / EU Method A.2, GLP study. The test item decomposes at about 300ºC.
Key value for chemical safety assessment
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.
