- Atm. press.:
- ca. 1 013.25 hPa
- Decomposition:
- no
- Conclusions:

- Executive summary:
A study was conducted according to OECD test guideline 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry (DSC 25 -500 °C). The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded. The test item had a boiling range at atmospheric pressure of 405- 455 °C.
Reference
Three measurements in aluminium crucibles with a hole showed an endothermic effect after melting in
the temperature range 405 -455 °C with an onset temperature of 440 °C.
