Results and discussion

Melting / freezing point
Key result
Melting / freezing pt.:
-57.4 °C
Atm. press.:
1 atm
Decomposition:
no
Sublimation:
no
Remarks on result:
not determinable
Remarks:
The sample does not display a freezing point on cooling. A melting point was not evident on heating. The sample shows a glass transition with an average onset of 215.9°K (-57.4°C). It is possible the sample has a melting or freezing point below -90°C. However, the glass transition indicates that the sample is amorphous rather than crystalline.

Applicant's summary and conclusion

Conclusions:
Glass transition with an average onset of 215.9°K (-57.4°C).
