Reference
Statement
The explosive properties of the test item was estimated based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3rd edition, 1999), where a set of criteria is compiled to identify materials being potential explosives.
Reactive Groups
The appraisal of the molecular structure indicates no risk of rapid decomposition. The test substance does not contain any of the structural features mentioned in the UN Recommendations. The occurrence of other chemical groups associated with explosive properties as described in the literatue was also considered. No such groups were present.
Oxygen Balance
The oxygen balance was calculated using the equation given in the UN Recommendations. Based on the molecular formula C42H61O5P and a molecular weight of 660.92 g/mol, the oxygen balance is approximately -267.5 which is below the limit of -200 requiring experimental testing.
Calorimetric Tests
The exothermic decomposition energy was determined using Differential Scanning Calorimetry (DSC) in a closed vessel. The decomposition energy (determined between room temperature and 500 °C) was found to be about 138 J/g, thus far below the UN limit of 500 J/g requiring the material to be tested according to EC test guideline A.14.
Conclusion
Applying the internationally recognised UN Recommendation criteria, the test item is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 had to be performed. Thus it can be concluded beyond a reasonable doubt, that the test material is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgement is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.
Description of key information
not explosive
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
There are no chemical groups associated with explosive properties present in the molecule, the calculated oxygen balance is less than -200 (-267.5) and the exothermic decomposition energy is less than 500 J/g (138 J/g).
Justification for classification or non-classification
The available data on explosive properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification:
Based on chemical structure the substance is not explosive.
