Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
