Results and discussion
Boiling point
- Atm. press.:
- 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- 212.8 °C
- Remarks on result:
- other: Decomposition occurred before boiling
Any other information on results incl. tables
DSC run was performed in the temperature range between 25°C and 400°C. The endothermic reaction at 101.7°C (melting point) was followed by an exothermic reaction at 212.8°C. This exothermic reaction was due to the decomposition of the test item. After the experiment the test item was molten, black and carbonized.
Applicant's summary and conclusion
- Conclusions:
- The test item decomposed before boiling.
- Executive summary:
The test item was analysed by Differential Scanning Calorimetry between 25°C and 400°C. The endothermic reaction at 101.7°C (melting point) was followed by an exothermic reaction at 212.8°C. This exothermic reaction was due to the decomposition of the test item.
Conclusion: No boiling point could be determined as decomposition of the test item was observed before boiling occurred.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
