- Remarks on result:
- other: In a DSC, ca. 40 to ca. 500 °C, according to OECD 113, a strong exothermic decomposition reaction is observed from 141 °C (closed metal vessel, V4A, heating rate 1 K/min), with a decomposition energy > 4450 J/g.
Sealed glass ampoule results:
No. | Sample Mass in mg | Temperature Range in °C | Type of effect | Energy in J/g |
1 | 27.0 | approx. 40 - approx. 70 | endothermic | |
265 - > 500 | exothermic | > 2400 | ||
2 | 24.3 | approx. 40 - approx. 70 | endothermic | |
269 - > 500 | exothermic | > 2450 |
An exothermic effect was observed in the temperature range beginning at 265 °C. The exothermic reaction was not finished at the end of the measurement range at 500 °C. The decomposition energy is more than 2400 J/g.
Closed metal vessel (V4A-steel) results:
No. | Sample Mass in mg | Temperature Range in °C | Type of effect | Energy in J/g |
1 | 103.6 | approx. 40 - approx. 70 | endothermic | |
141 - > 500 | exothermic | > 4450 |
