- Key result
- Melting / freezing pt.:
- 101 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 161 - <= 450 °C
- Conclusions:
- The melting point of the test item is 101 °C.
- Executive summary:
The melting point of the test item determined by DSC measurement according to ATSM E 537 -76 is 101 °C. Between 161 °C and 450 °C the substance shows a complex exothermic decomposition.
Reference
The substance shows first an endothermic melting signal with an onset at 101 °C. Between 161 °C and 450 °C the substance shows a complex exothermic decomposition with several peaks and an overall energy content of 1375 J/g. The most prominent peak of this group is the first one with an onset temperature of 190 °C and a maximum heat flow of 1.4 W/g at 219 °C.
Description of key information
The melting point of the test item determined by DSC measurement according to ATSM E 537 -76 is 101 °C. Between 161 °C and 450 °C the substance shows a complex exothermic decomposition.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 101 °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.
