Results and discussion
Boiling point
- Atm. press.:
- 99.4 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 200 °C
- Remarks on result:
- other: The test substance decomposed before boiling. Decomposition was indicated by change of colour starting at about 200 °C. The decomposed test substance boiled from about 290 °C on. Therefore no boiling point could be determined.
Any other information on results incl. tables
Starting at 200 °C the colour of the test substance changed from yellowish to brown at 220 °C, to dark brown at 230 °C and to black at approximately 255 °C.
About 290 °C the test substance started boiling, but due to the black colour of the test substance the capillary was no longer observable. At 300 °C the test substance boiled over.
Therefore the boiling point of test substance was estimated by a Atom/Fragment Contribution Method by using MPBPWIN Verion1.41©2000, U.S. Environmental Protection Agency. The estimated value was 697 °C.
Applicant's summary and conclusion
- Conclusions:
- No boiling point could be determined and therefore the boiling point of test substance was estimated by a Atom/Fragment Contribution Method. The boiling point of the test substance was estimated to be 697 °C.
