Applicant's summary and conclusion
- Conclusions:
- The test item does not boil under test conditions
- Executive summary:
The determination of the boiling point/ boiling range of the test item was performed according to the EEC Directive 92/69, A.2 "Boiling temperature", December 1992 and to the OECD Guideline No. 103:" Boiling point", adopted July 27, 1995.
Using thermal analysis, no endothermic peaks were detected in the temperature range between 25 °C and 400 °C (heating rate 20 K/min) from which boiling could be deduced.
During the preliminary test, an endothermic heat effect was observed between about 80 °C and 180 °C. Starting at about 320 °C an exothermic reaction was observed. After the experiment the test item was dark brown and still a powder. A second DSC run with reduced heating rate of 10 K/min was performed to confirm the result found during the preliminary test.
In conclusion, the test item does not boil under the applied conditions
