Results and Discussions
Preliminary Test
The preliminary test was done from 25 °C to 400 °C with a heating rate of 20 °C/min. A first endothermic heat effect, the melting, was observed at 32.6 °C. A second endothermic heat effect, the boiling, was detected at 298.7 °C. After the experiment, the sample had lost 99.8% of its mass no residue remained in the sample cup.
Main Tests
In order to determine the boiling point more precisely, further DSC-runs were recorded between 220 °C and 350 °C with a heating rate of 10 °C/min. During these runs, the boiling point was determined to be 308.4 °C in both runs. The samples lost 97.2% and 96.1% of their mass, and no residue remained in the sample cups.
Description of key information
The boiling point of the test item was determined to be 308.4 °C, which is equal to 581.6 K. This result was obtained using Differential Scanning Calorimetry (Thermal Analysis) method. The atmospheric pressure during the measurements was 100.0 kPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 308.4 °C
