Boiling point
- Remarks on result:
- not determinable
Any other information on results incl. tables
Three DSC measurements were carried out. In all measurements, endothermic events between 83.28 °C and 220.93 °C were detected. This could be a sign of splitting of a chemical compound, as no signs of melting were seen during the pre-test and when the second crucible was opened.
Afterwards at measurement 1 and 3 from 263.50 °C, an endothermic event with zigzag peaks can be seen, according to the pre-test this can be indicated as melting under decomposition.
The boiling in the pre-test could be a boiling point of the decomposition product.
Since the test item melts under decomposition, no boiling point can be determined under these test circumstances.
Applicant's summary and conclusion
- Conclusions:
- No boiling point of the test substance under the test circumstances could be determined as the test substance decomposed during melting.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
