Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling Point)
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)

Decomp. temp.:
ca. 132 °C
Remarks on result:
other: The test item changed from brown, to dark brown, to black over the temperature range 132 °C to 320 °C.

Results of pre test:

Observations

Temperature

Test item in aluminium block

23.8 °C

Melting began under decomposition, colour

was darker

132 °C

               

Melting end under decomposition, colour

was darker

133 °C

After melting, colour brown

137 °C

Colour a bit darker

240 °C

Colour strong darker

319 °C

Colour dark brown nearly to black

320 °C

Heating up to 390 °C as the test item was black. The test item decomposed.

 

In the pre-test, the test item showed signs of decomposition during melting process indicated by colour change.

The determination of melting and boiling point of the test item AF-317 could not be determined because of decomposition during melting process.

Description of key information

No boiling observed, decomposition started at 132 °C (OECD 103, pre-test, capillary tube)

Key value for chemical safety assessment
