Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The test item showed a sharp exothermic effect in the temperature range of 180 - 240 °C with a mean decomposition energy of -320 J/g, which was directly followed by an endothermic signal in the temperature range of 230 - 360 °C. The endothermic signal may result from the loss of gaseous decomposition products. Due to the fact that the test item decomposes before reaching its boiling point, the boiling point cannot be determined.

No further thermal effects were observed up to the test end temperature of 500 °C.

Description of key information

180 °C (decomposition, OECD 102, A.1.)

Key value for chemical safety assessment

Additional information

The test item decomposes before reaching its boiling point and has no boiling point up to the decomposition temperature of 180 °C as determined by differential scanning calorimetry.
