- Executive summary:
A study was peformed according to OECD TG 103, Commission Regulation (EC) No. 440/2008 method A.2. and EPA OPPTS 830.7220 in order to determine the boiling point of the test item by using the differential scanning calorimetry method (DSC). The test item was weighted into a one-way 40 µL aluminium crucible, sealed and heated in the DSC device from room temperature to 500 °C with a heating rate of 10 °C/min. As reference sample an empty crucible was used. The test was performed twice. The heat flow and any thermal events as well as the onset and the related energy were recorded and presented in a thermogram (software STARe). The boiling point of the test item was determined to be in the range of 245.0 and 260.4 °C (518.1 to 533.6 K) at a pressure of 1000.7 hPa.
Reference
Appearance of the sample
Before the test the appearance of the test item was white solid. After the experiments the test item was evaporated from the crucible.
Results
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. The DSC measurements were performed twice.
