Any other information on results incl. tables

Preliminary TGA

From 300°C upwards the weight of the sample decreased significantly. At 367°C, the sample weight had decreased by 25%. After the experiment, a brown/black residue was observed on the lid of the sample container and a brown/black residue remained in the sample container

 

DSC

With all experiments, an exothermic decomposition effect starting at 150°C was observed. After the experiments, a brown/black residue remained at the bottom of the sample container and some residue was observed at the outside of the sample lid. The sample lid was opened due to pressure.  

 

Since the extrapolated onset temperature of the exothermic decomposition is below 500°C and the exothermic decomposition energy is more than 500 J/g, the test substance was considered potentially explosive.

 

Table: DSC measurements

 

	Extrapolated onset temperature	Exothermic decomposition energy
Experiment I	191.36°C	889.9 J/g
Experiment II	196.60°C	1015.0 J/g
Experiment III	190.99°C	906.3 J/g
Mean	193°C	937 J/g

 

 

Applicant's summary and conclusion

Interpretation of results:

non explosive

Remarks:

Migrated information

Conclusions:

During the DSC screening test, exothermic decomposition of the test substance was observed at a temperature of 193°C (exothermic decomposition energy: 937 J/g). In the full test, it was determined that the substance is not explosive when exposed to thermal stress or to mechanical stress (by shock). Therefore, OS 2600 should be considered to present no danger of explosion. The study was performed in accordance with EC A.14, UN and EPA OPPTS 830.6316 guidelines and according to the principles of GLP.
