Any other information on results incl. tables
Examination of the structural formula for the sample indicates:
• The structure contains contiguous nitrogen atoms which are associated with explosive properties (Table 7.1).
• The oxygen is not bound in energetic functional groups – it is bound in C-O-C groups which do not possess explosive behaviour. The oxygen balance is -135 – above the criteria for consideration (-200). However, there would be expected to be some energetic behaviour associated with the nitrogen ring atoms (although this would not be expected to be a particularly dramatic behaviour as would be expected for a tetrazole).
• Differential scanning calorimetry conducted on the sample indicated that the total heat of decomposition is < 500 J.g-1.
Based on the results of the differential scanning calorimeter test, it is beyond reasonable doubt that the material will not exhibit explosive properties. The conduct of furtherexplosive properties testing is therefore not considered appropriate.
The full profile for the experiment is provided in Graph 1 (attached).
The sample was observed to undergo an exothermic event from 198.7°C which had a heat of decomposition of -282.1 J.g-1. A second exothermic event was then observed to commence from 275.1°C which had a heat of decomposition of -72.7 J.g-1. No further significant energetic events were noted up to 500°C.
The total heat of decomposition was therefore -354.8 J.g-1.
Applicant's summary and conclusion
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- Based on examination of the structural formula and the results of the differential scanning calorimeter test, it is beyond reasonable doubt that the material will not exhibit explosive properties. The conduct of further explosive properties testing was therefore not considered appropriate.
- Executive summary:
A GLP-compliant study has been conducted in compliance with EU method A14 of Directive 92/69/EEC. Based on examination of the structural formula and the results of the differential scanning calorimeter test, it is beyond reasonable doubt that the material will not exhibit explosive properties.
