Results and discussion
Boiling point
- Decomposition:
- yes
- Decomp. temp.:
- >= 216 °C
Any other information on results incl. tables
In air oxidation occurs before boiling, an exothermic effect with an onset of 489 K (216 °C). In nitrogen the product showed a wide endothermic effect at temperature interval 525-723 (252-450 °C) which can be interpreted as both boiling and decomposition of the product; boiling of the low Mw part, which followed by decomposition of the higher Mw part. After measurement the crucible had a yellow-brown colour, indication of decomposition of the product during heating at the measurement temperature.
Applicant's summary and conclusion
- Conclusions:
- In air oxidation occurs before boiling
In nitrogen occurs both boiling and decomposition - Executive summary:
In air oxidation occurs before boiling
In nitrogen occurs both boiling and decomposition
