SELF REACTIVE SUBSTANCE (CLP 2.8)

Results of trial 1 and trial 2:

- Trial 1 (26.9 mg): At a heating rate of 3 K/min, an exothermic reaction started at 215 °C with a heat release of about 13 kJ/kg

- Trial 2 (28.1 mg): At a heating rate of 3 K/min, no exothermic reaction could be measured under Argon-Atmosphere. The first exothermic reaction (trial 1) was an oxidizing reaction with the residual oxygen in the glass container. It disappears under argon. Based on the heat of decomposition and onset-temperature it is expected that SADT is > 75 °C.

CORROSIVE TO METALS (CLP 2.16)

The structural formula of 2,2-dimethylpropane-1,3-diyl dibenzoate shows no chemical groups in the molecule, that causes a corrosivity to metals and, thus, it can be concluded that 2,2-dimethylpropane-1,3-diyl dibenzoate is not corrosive to metals in the sense of the test guideline UN C.1 which is cited in GHS chapter 2.16.

 

Conclusions:
2,2-Dimethylpropane-1,3-diyl dibenzoate is stable, because it shows no self-reactive or self-heating properties, there are no exothermic reactions up to >300 °C and it is not corrosive to metals.
Executive summary:

2,2-Dimethylpropane-1,3-diyl dibenzoate is stable, because it shows no self-reactive (DTA) or self-heating (UN N.4) properties, there are no exothermic reactions up to > 300 °C (distillation method) and it is not corrosive to metals (UN 37.4).

Description of key information

2,2-Dimethylpropane-1,3-diyl dibenzoate is stable, because it shows no self-reactive or self-heating properties, there are no exothermic reactions up to >300 °C and it is not corrosive to metals.

Additional information

Justification for classification or non-classification

2,2-Dimethylpropane-1,3-diyl dibenzoate does not need to be classified, because it is stable and shows no corrosive properties.
