Results and discussion
Boiling point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 135 °C
- Remarks on result:
- other: no boiling point up to its decomposition starting at a temperature of approx. 135 °C at atmospheric pressure (1016 hPa)
Any other information on results incl. tables
In the temperature range of 50 °C – 180 °C, an endothermic effect was observed, which was directly followed by an exothermic effect in the temperature range of 180 – 210 °C, with a mean decomposition energy of -200 J/g. No further thermal effects were observed up to the test end temperature of 500 °C.
