Reference
Melting Point / Melting Range (DSC):
One measurement in an aluminium crucible with a hole showed an endothermic effect (melting) in the temperature range -10 °C to +15 °C with an onset temperature of -6.3 °C.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 |
32285 | -6.29 | -10 - +15 | Aluminium crucible with a hole |
The test item had a mean melting point of -6.3°C under atmospheric conditions.
Description of key information
The freezing point of the test item was determined to be -6.3 °C under atmospheric conditions
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -6.3 °C
Additional information
The freezing point of the test item is influenced by its high water content.
