Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
AES melted and decomposed (starting at about 150°C) before boiling occured.
Executive summary:

Between 141 °C and 148 °C the test item rose in the capillary tube and bubbled for some seconds. However a current stream of bubbles could not be observed. Above 150 °C the melt evolved black spots and later changed to greyish. At about 300 °C the test item turned orange. At about 350 °C black spots were observed. After the test, a dark orange and partly black residue remained.
