Results and discussion
Boiling point
- Key result
- Boiling pt.:
- >= 173 °C
- Atm. press.:
- ca. 1 026 mBar
- Decomposition:
- yes
- Decomp. temp.:
- >= 173 °C
Any other information on results incl. tables
As the boiling tubes were heated at 1 degC/minute, the samples were observed to darken at temperatures above approximately 173°C, indicating decomposition. When heating was continued beyond this temperature in the preliminary trial, the sample continued to darken when heated to 360˚C where it did not boil.
Applicant's summary and conclusion
- Conclusions:
- It was not possible to determine the boiling temperature of the test substance as it decomposed at temperatures above approximately 173°C without boiling.
- Executive summary:
It was not possible to determine the boiling temperature of the test substance as it decomposed at temperatures above approximately 173°C without boiling.
