Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- ca. 0 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: pour point
- Remarks:
- The pour point, the lowest temeprature at which the test material barely flows is at approximately 0 °C.
Any other information on results incl. tables
Measurements were made with differential scanning calorimetry in a temperature range between -100 and + 60 °C, but there was no possibility to determine a fixed melting point because the substance congealed amorphous and glassy. In the DSC diagrams there was only a glas transition at approximately -50 °C.
The pour point, the lowest temperature at which the testing material barely flows was at approx. 0 °C.
Applicant's summary and conclusion
- Conclusions:
- A pour point was determined at approximately 0 °C.
