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.
