The sample was measured by differential scanning calorimeter (DSC)
Tm: melting temperature at 2nd heating (peak maximum)
The melting point of the sample was measured by DSC. The maximum endothermic peak was observed at 98.00 ºC and 97.86 ºC for the first
and second test respectively. The melting point is reported as the average value of the test results, 97. 9 ºC.
After the experiment, the sample appeared to be melted in the sample container.
Melting point average: 97.9 ºC (371. l K)
Description of key information
Melting temperature of ESA was (97.9 ± 0.5) ºC {(371.1 ± 0.5) K} at 101.3 kPa by DSC.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 97.9 °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.
