- Executive summary:
A study was conducted according to OECD test guideline 103 and according to the annex to directive 92/69/EEC 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 were heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles were used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released was measured and recorded. The test item had a boiling range at atmospheric pressure of 440 - 443 °C.
Reference
Three measurements in aluminium crucibles with a hole showed an endothermic effect after melting in
the temperature range 390 -470 °C with an onset temperature of 440 °C.
