- Executive summary:
A study was conducted according to OECD test guideline 103 and Regulation (EC) No 440/2008 method A.2. The boiling point was determined by differential scanning calorimetry (DSC). The test item and the empty reference crucible were heated up from the starting temperature (ambient) to the final temperature (500 °C) at a constant heating rate (10 K/min) 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. Three measurements showed an endothermal effect (boiling) in the temperature range of 360 - 475 °C. The boiling range of the test item was determined to be between 417 and 427 °C.
Reference
Three measurements showed an endothermal effect (boiling) in the temperature range of 360 - 475 °C.
