- Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 180 °C
- Remarks on result:
- not determinable
- Conclusions:
- The boiling temperature was not determinable as the test item was determined to decompose before melting completely
Reference
The test item showed the initial stages of melting, but did not melt completely. At approximately 180°C, evolution of gas from the partially molten sample was observed to force the sample up the capillary tube, indicating decomposition.
For confirmatory purposes, differential scanning calorimetry (DSC) was also conducted using a Mettler-Toledo FP900 Thermosystem with FP85 DTA/DSC measuring cell, in an air atmosphere at a heating rate of 20°C/minute. The DSC trace showed a broad shallow endotherm below 150°C, followed by significant exotherms from approximately 180˚C which were consistent with the indication of decomposition in the metal block test.
Description of key information
The boiling temperature was not determinable as the test item decomposes before completely melting.
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.
