Results and discussion
Boiling point
- Key result
- Atm. press.:
- ca. 1 017 hPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 130 °C
- Remarks on result:
- other: No boiling point up to its decomposition starting at a temperature of approx. 130 °C
Any other information on results incl. tables
During the heating phase a small endothermic effect was observed starting at a temperature of 190 °C, which was directly followed by a sharp exothermic effect starting at a temperature of 210 °C. The average energy of the exothermic effect was -200 J/g. A second small endothermic effect was observed directly after the exothermic effect starting at a temperature of 220 °C. During the test the test item decomposed and swelled out of the crucible.
