- 218 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- >= 218 °C
- Conclusions:
- The test substance melted under decomposition at 218 °C in a test according to OECD Guideline 102 (differential scanning calorimetry method and capillary method)
Reference
During the thermal stability test, the test item showed no exothermal decomposition up to the maximum temperature of 400 °C.
During the melting point test, the test item changed the color near the melting point, which indicates beginning decomposition.
Three DSC-runs showed one or two endothermic effects, respectively, in temperature ranges of 130 - 165 °C and 205 - 250 °C with onset temperatures of 138 °C and 218 °C, respectively.
In the capillary measurement, the test item started melting at 219.7 °C.
The endothermic process in the range of 130 - 165 °C is assumed to be caused by the release of crystal water.
Description of key information
Melting point (under decomposition) = 218 °C (OECD Guideline 102, differential scanning calorimetry method and capillary method)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 218 °C
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.
