Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- non explosive
Additional information
As a screening method for the determination of explosive properties a differential scanning calorimetry (DSC) under nitrogen was performed.
If the decomposition energy is below 500 J/g a main test for explosive properties is unnecessary.
For the measurement in a closed glass crucible about 12 mg of the test item were used. The test item and the standard material (aluminium oxide) were heated up from ambient to the final temperature (500°C) at a constant heating rate (3 K/min) in a defined atmosphere (nitrogen).
The quantity of heat absorbed or released was measured and recorded.
The DSC-measurement in a closed glass crucible with the test item showed 2 exothermic effects up to the end of the measurement at 500°C. The first exothermic effect within the temperature range of 170°C to 220°C showed a heat of decomposition of 148 J/g and the second exothermic effect within the temperature range of 305°C to 360°C showed a heat of decomposition of 46 J/g.
Explosive Properties
The heat of decomposition was below 500 J/g. Therefore the test on explosive properties was not necessary.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
