- Conclusions:
- The boiling range of the test item was determined to be in the range from 164.5 to 178.1 °C.
- 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 to determine the boiling point of the test item using differential scanning calorimetry. An endothermic effect was detected in the range of 164.5 to 178.1 °C which is assigned to the boiling of the test item. Therefore, the boiling range of the test item was determined to be in the range from 164.5 to 178.1 °C.
Reference
Before the test the appearance of the test item was colourless, liquid. After the experiments the crucible was empty.
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.
| Onset of effect (°C) | Endset of effect (°C) | Energy (J/g) |
Sample 1 | 164.36 | 177.28 | -365.92 |
Sample 2 | 164.72 | 178.95 | -343.91 |
Mean | 165.54 | 178.12 | -354.92 |
Description of key information
