Method:

other: Structural evaluation and oxygen balance

Parameter:

other: Structural evaluation and oxygen balance

Result:

other: Predicted not to have explosive properties

Remarks on result:

not measured/tested

Remarks:

Structural assessment indicated no chemical groups associated with explosive properties.

Reactive Groups

The appraisal of the molecular structure indicates no risk of rapid decomposition. The test material 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 literature was also considered. No such groups were present.

The chlorine is only linked directly to carbon and therefore does not indicate a risk for explosive properties.

 

Oxygen Balance

The oxygen balance can only be estimated roughly based on the equation given in the UN Recommendations as the test material contains other elements than CHO. Taking these three elements into consideration, the oxygen balance is below -200.

 

Calorimetric Tests

The exothermic decomposition energy was determined using Differential Scanning Calorimetry in a closed, gold plated high pressure vessel (DSC). No sharp peaks were observed. One flat and very broad peak was detected between room temperature and 500 °C. The total decomposition energy (ΔHDEC) determined between room temperature and 500 °C) was found to be about 410 J/g, thus being near the UN limit of 500 J/g. The calorimetric test is of special importance for the evaluation of compounds containing chemical groups associated with explosive properties which is not the case for the present test material.

Interpretation of results:

other: Not classified according to EU criteria.

Conclusions:

The test material is not considered explosive.

Executive summary:

The explosive properties of the test material were assessed using an appraisal of the reactive groups, calculation of the oxygen balance and calorimetric tests.

Based on the results of the assessment the test material is not to be classified as explosive and no experimental determination according to EC Guideline A.14 has to be performed. The result of the calorimetric test is not considered relevant for this substance as there are no sharp peaks and the compound does not contain chemical groups associated with explosive properties.

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.

Description of key information

The test material is not considered explosive.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

The explosive properties of the test material were assessed using an appraisal of the reactive groups, calculation of the oxygen balance and calorimetric tests. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

Based on the results of the assessment the test material is not to be classified as explosive and no experimental determination according to EC Guideline A.14 has to be performed. The result of the calorimetric test is not considered relevant for this substance as there are no sharp peaks and the compound does not contain chemical groups associated with explosive properties.

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.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to explosive properties.
