- Key result
- Melting / freezing pt.:
- > 400 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 140 °C
- Remarks on result:
- other: The test item has no melting point. The test item decomposed.
- Conclusions:
- The test item has no melting point. The test item decomposed.
- Executive summary:
At ambient temperature the test item is solid.
Two measurements in a closed glass crucible with the test item showed a broad endothermal effect in the temperature range 110 to 160°C. Two exothermal effects were detected in the temperature ranpe 175 - 195°C with an energy release of 11 J/g (1 st measurement) and 14 J/g (2nd measurement), respectively, and in the temperature range 245 - 295°C with an energy release of 250 J/g (1st measurement) and 243 J/g (2nd measurement), respectively. About 2/3 of the weight of the test item remained in the crucible after measurement showing a black residue
The endothermal effect was further investigated with the capillary method.
Starting at approx. 91°C some liquid distilled off, and condensed at the cool part of the capillary outside the heating block. The solid material remained unchanged without melting up to approx. 245-249°C. Starting above 245 °C the red test item discoloured to black up to 277-279°C.
Thus it was concluded, that the test item showed no melting. The test item decomposed
