- negative (not further specified)
- Remarks:
- In DSC no exothermic energy more than 500 J/g.
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- Diisobutylaluminium hydride has no explosive properties.
- Executive summary:
The method is welldescribed and well accepted for this endpoint. The purity of the substance is not mentioned in the report.
Diisobutylaluminium hydride has no explosive properties.
Reference
See DSC scan in attached background material.
Diisobutylaluminium hydride(DIBAL-H) pure gives an endothermic effect during heating from around 80 to 280°C, followed by a sharp exothermic effect of the diisobutylaluminium hydride decomposition. The total heat of the exothermic effect is 371 J/g. This is below the 500 J/g limit. So testing on explosive properties does not have to be performed.
Description of key information
Diisobutylaluminium hydride has no explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
