Any other information on results incl. tables

Assessment of the decomposition energy using DSC gave results that decomposition commenced starting at 210°C, with a released energy of -330 J/g.The regulatory position, specifically the REACHRegulation with regards to explosivity is that a study does not need to be conducted if:

– there are no chemical groups associated with explosive properties present in the molecule; or
– the substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than –200; or
– the organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 ºC; or
– for mixtures of inorganic oxidising substances (UN Division 5.1) with organic materials, the concentration of the inorganic oxidising substance is:
– less than 15 %, by mass, if assigned to UN Packaging Group I (high hazard) or II (medium hazard)
– less than 30 %, by mass, if assigned to UN Packaging Group III (low hazard).

As decomposition occurred from 210°C, with a released energy of -330 J/g, this is below the specified limits with the REACH regulation. As such, the substance is determined not to pose a hazard for explosivity.

Conclusions:

Assessment of the decomposition energy using DSC gave results that decomposition commenced starting at 210°C, with a released energy of -330 J/g. The regulatory position, specifically the REACHRegulation with regards to explosivity is that a study does not need to be conducted if:
