Link to relevant study record(s)
- Endpoint:
- thermal stability
- Remarks:
- Heat of decomposition
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2015-10-13 to 2016-02-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- ASTM E537
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E537 "The Thermal Stability of Chemicals by Differential Scanning Calorimetry".
- Deviations:
- no
- Principles of method if other than guideline:
- The test was carried out using Differential Scanning Calorimetry (DSC), which provides a suitable technique for measuring the exothermic decomposition energy as required for screening potential explosive or self-reactive substances.
The test sample is heated through a specified temperature range at a constant rate, the heat flow measured and the results displayed as a plot of power versus temperature/time. The resulting thermogram is analysed for the presence of exothermic events which may be due to decomposition. The energy output (J/g) is calculated by integration of the areas beneath the exothermic peaks. - GLP compliance:
- yes
- Test substance thermally stable:
- yes
- Key result
- Operating temp.:
- >= 120 - <= 190 °C
- Remarks on result:
- other: heat of decomposition
- Remarks:
- 63 J/g
- Conclusions:
- The thermogram shows only a small exothermic peak within the range 120 - 190°C. The total normalized energy output from this exothermic event, i.e. the heat of decomposition, is 63 J/g.
- Executive summary:
The test sample was heated from 25°C to 500°C at 5°C/min, the heat flow measured and the results displayed as a plot of power versus temperature/time. The resulting thermogram was analysed for the presence of exothermic events which may be due to decomposition. The energy output (J/g) was calculated by integration of the areas beneath the exothermic peaks. The thermogram showed only a small exothermic peak within the range 120 - 190°C. The total normalized energy output from this exothermic event, i.e. the heat of decomposition, was 63 J/g.
Reference
The thermogram shows only a small exothermic peak within the range 120 - 190°C. The total normalized energy output from this exothermic event, i.e. the heat of decomposition, is 63 J/g.
Description of key information
The thermal stability was tested using Differential Scanning Calorimetry (DSC). Only a small exothermic peak within the range 120 - 190°C was observed, with a heat of decomposition 63 J/g.
