Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Parameter:
- other: Explosive (not specified)
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Remarks:
- In DSC no exothermic energy more than 500 J/g.
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- Butylethylmagnesium has no explosive properties.
- Executive summary:
Measurement of the total heat of decomposition is a well accepted technique mentioned in UN specification to establish the possible explosiveness. With the measured very low total heat of decomposition butylethylmagnesium has no explosive properties.
Reference
See Setaram C80 scan in attached background material.
No leakage was detected by measuring the weight of the pan before and after the experiments.
Total heat of decomposition is 18.5 J/g. This is the sum of the two exothermal effects minus the effect of the small endothermal effect located in between the two exothermal effects.
The onset temperature of the exothermal effect is 197°C.
Total heat of decomposition of 20% butylethylmagnesium in heptane is 18.5 J/g. This is a very low value or, in other words, a far too low value to give a dangerous level of self heating.
Description of key information
Butylethylmagnesium has no explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
Measurement of the total heat of decomposition is a well accepted technique mentioned in UN specification to establish the possible explosiveness. With the measured very low total heat of decomposition butylethylmagnesium has no explosive properties.
