Results and discussion
Boiling point
- Atm. press.:
- 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- > 325 °C
- Remarks on result:
- other: boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started.
Any other information on results incl. tables
Preliminary test: From approximately 350°C upwards the weight of the sample decreased significantly. At 436°C, the sample weight had decreased by 25%. After the experiment, a black molten residue (original colour: violet) remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test substance.
Main study: Starting at 325°C a relatively broad endothermic effect was found. Reaction and/or decomposition of the test substance caused most likely this effect. After the experiment, a black molten residue remained in the sample container. |
Applicant's summary and conclusion
- Conclusions:
- Reaction and/or decomposition of the test substance were observed above 325°C (598K): boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started. Therefore, the test substance has no boiling temperature.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
