- Key result
- Melting / freezing pt.:
- 189 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 265 - <= 337 °C
- Conclusions:
- The melting point of the test item is 189 °C.
- Executive summary:
The melting point of the test item, determined by DSC measurement and according to ATSM E 537 -76, is 189 °C. Between 265 °C and 337 °C the substance shows a slightly exothermic decomposition with an energy content of 47 J/g. The exothermic event is not critical.
Reference
The substance shows a first endothermic melting signal with an onset at 189 °C. Between 265 °C and 337 °C the substance shows a slightly exothermic decomposition with an energy release of 47 J/g with an onset at 271 °C. The maximum heat flow of 0.2 W/g was measured at 290 °C.
Description of key information
The melting point of the test item, determined by DSC measurement and according to ATSM E 537 -76, is 189 °C. Between 265 °C and 337 °C the substance shows a slightly exothermic decomposition with an energy content of 47 J/g. The exothermic event is not critical.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 189 °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.
