Results and Discussion
The temperature range for the investigation of the melting point was fixed between 40 °C and 140 °C. A sharp endothermic signal was recognizable in the range of 67-70 °C. For two runs the following melting points were resulting:
run 1: 67,46 °C
run 2: 67,27 °C
The evaluation of endothermic signals for both runs results in a middle melting point of the test item of 67.4 °C (onset temperatures).
Description of key information
Melting point: 67.4 °C at 1021.25 hPa (EU Method A.1, differential scanning calorimetry)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 67.4 °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.
