Description of key information

2, 4-Dichloronitrobenzene does not show explosive properties as tested according to the UN test series 1 and 2 (Currenta, 2009).

Key value for chemical safety assessment

non explosive

Additional information

Justification for classification or non-classification

Differential Thermal Analysis

Onset of exotherm reaction: 320 °C

Heat release: 1650 J/g

Trauzl Test (UN F.3)

2, 4-Dichloronitrobenzene exhibits some explosive power and further tests have to be performed.

Propagation of detonation (UN A.1, BAM 50/60 steel tube test)

2, 4-Dichloronitrobenzene is not able to propagate a detonation. From these findings it can be concluded that 2, 4-Dichloronitrobenzene is not sensitive to detonative shock (UN 2(a)).

Koenen Test (UN 2(b))

2, 4-Dichloronitrobenzene shows no violent effect on heating under confinement.

Time-pressure-test (UN 1(c), UN 2 (c))

2, 4-Dichloronitrobenzene shows no likelihood of deflagration.
