Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- -62.7 °C
- Remarks on result:
- other: Instead of the term „melting point" the term „transition point" is used, as the energy of the endothermic effects was untypically low (5 to 10 J/g) for a melting point.
Any other information on results incl. tables
Melting (Transition) Point / Range (DSC)
Two DSC measurements in aluminium crucibles with a hole showed an endothermic effect in the temperature range -70 °C to 20 °C with an onset temperature of around 62 °C while the test item was heated up. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline.
| Ident-No. | Onset / °C | Temperature range / °C | Crucible |
| 30458 | -62.48 | -70 to -20 | Aluminium with a hole |
| 30481 | -62.99 | -70 to -45 | Aluminium with a hole |
The test item has a mean transition point [*] of -62.7 °C.
Applicant's summary and conclusion
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.
