- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 67/548/EEC
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 351 °C
- Atm. press.:
- 1 013.3 hPa
- Conclusions:
- The boiling point of the test item at atmospheric pressure (1013,3 hPa) is 351 °C.
- Executive summary:
The determination of the boiling point / boiling range is carried out by differential scanning calorimetry (DSC). In a defined atmosphere (nitrogen) the test item was heated up from ambient temperature to the final temperature (450 °C) at a constant heating rate (10 K/min). The quantity of heat absorbed or released was measured and recorded. Aluminium crucibles with a small hole were used as containers for the test item and as empty reference crucible. Approx. 5 -6 mg of the test item was used. The boiling point of the test item at atmospheric pressure (1013,3 hPa) is 351 °C.
Reference
Boiling Point/ Boiling Range (DSC)
Two measurements in aluminium crucibles with a hole showed an endothermic effect after melting in the temperature range 310- 360 °C with an onset temperature of approximately 350 °C.
