Results

1.1                       Thermal stability (DSC)

In the temperature range at 110 – 160 °C an exothermic effect can be observed with an energy release of -40 J/g. A second exothermal signal appears in the temperature range at 200 – 330 °C with an energy release of approximately -340 J/g.

Table1:    Results of the DSC-measurements

No.	Sample weight / mg	Onset / °C	Energy / J/g	Remark
PN10292	3.40	110 200	-40 (exothermic) -320 (exothermic)	Figure 1
PN10286	7.08	110 220	-30 (exothermic) -350 (exothermic)	Figure 2

Due to the decomposition energy being below the threshold of -500 J/g, further tests for explosive properties did not have to be performed.

In the DSC-measurement the energy of the exothermic decomposition of the test item N,N-Dimethyloctan-1-amine was < 500 J/g. Therefore, further tests for explosive properties had not to be performed.

According to the results of the test on thermal stability and explosive properties, the test item is classified as following:

UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively.

Interpretation of results:

non explosive

Conclusions:

In the DSC-measurement the energy of the exothermic decomposition of the test item N,N-Dimethyloctan-1-amine was < 500 J/g. Therefore, further tests for explosive properties had not to be performed.
