- Executive summary:
An experimental study was performed to determine the boiling point of the test item according to Regulation (EC) No 440/2008 Method A.2. and OECD Test Guidelines 103 using differential scanning calorimetry. The test item was heated from room temperature to 500 °C with 10 °C/min heating rate. The boiling point was determined in the range of 377.6 – 415.8 °C at atmospheric pressure (99.27 kPa). The sample was a colourless liquid before the measurement. After the experiments the test item became a gray melt in the crucible. Based on the thermograms and the appearance of the test item after the tests, it is concluded that the test item decomposes after boiling.
Reference
The evaluation of the data was performed using the software STARe. As result, a thermogram was obtained in which the heat flow of the investigated sample is given as a function of the temperature. By integrating the area under the heat flow signals, the enthalpy of the process was obtained.
Using a linear heating rate of 10 °C/min the boiling point of the test item was determined to be in the range of 377.6 – 415.8 °C (650.7 – 688.9 K) at atmospheric pressure (99.27 kPa). Based on the thermograms and the appearance of the test item after the tests, it is concluded that the test item decomposes after boiling.
