Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
flash point of flammable liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Key result
Decomposition:
yes
Decomp. temp.:
269 °C

Based on this observation and the high standard deviation of the replicate measurements the 269 °C is considered to be a decomposition temperature.

Conclusions:
Based on this observation and the high standard deviation of the replicate measurements the 269 °C is considered to be a decomposition temperature.
Executive summary:

The melting point of a test item is defined as the temperature at which phase transition from a solid to liquid state takes place at normal atmospheric pressure. For the determination of the melting point, the capillary method was used. A small amount of the test item was heated in the electronic controlled sample block and the temperature around the sample was displayed. The melting point was determined based on thermo-optical changes, while raising the temperature. The photosensors continuously measured the intensity of the light transmitted through the samples.

Based on this observation and the high standard deviation of the replicate measurements the 269 °C is considered to be a decomposition temperature.
