Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

During the heating phase an endothermic effect was observed in the temperature range of 250 - 360 °C. Due to the fact that this effect was very broad, additional measurements by means of the capillary method were performed.

For this purpose, three capillaries were filled up to a height of 5-6 mm with the test item. The temperature was increased starting at 25°C with a heating rate of 10K/min up to 275 °C.

Up to a temperature of 267 °C no changes of the test item could be observed. At 267.7 °C the colour of the test item changed to black. At 272.1 °C the test item started to evaporate and ascended in the capillary. At 275.4 °C the test item was completely evaporated and the measurement was stopped.

The test item shows a decomposition and evaporation starting at 268 °C.

Up to a temperature of 267 °C no changes of the test item could be observed. At 267.7 °C the colour of the test item changed to black. At 272.1 °C the test item started to evaporate and ascended in the capillary. At 275.4 °C the test item was completely evaporated and the measurement was stopped.

Under consideration of both measurements (DSC and capillary) the test item has no melting point up to 500 °C. The melting/freezing point is <-100°C.
