- Name Bromo(hexahydro-2H-azepin-2-onato-N)magnesium
Batch no. 13081411
Appearance white flakes - Atm. press.:
- 1 Bar
- Decomposition:
- yes
- Decomp. temp.:
- 216 °C
- Conclusions:
- The boiling point should have been determined via DSC (differential scanning calorime-try)
In all measurements an endothermic behavior from 227 – 274 °C was observed evaluated with the event marker function in the first test series and with the onset function in the second test series.
Decomposition starts after the melting point at 216 °C (lowest value) evaluated with the event marker function, confirmed with additionally measurements.
The melting point should be stated in a range of 57.34 – 61.67 °C with no signs of de-composition (evaluated with the onset function).
In a first test series a possible decomposition was observed beginning at 59.17 (lowest value) as the additional measurements confirm the start of decomposition after the melt-ing point these observations can be discarded.
As decomposition was observed after melting beginning at 216 °C, a determination of the boiling point is technically not feasible.
No observations were made which might cause doubts on the validity of the study out-come. Therefore, the result of the study is considered valid. - Executive summary:
A boiling point of Bromo(hexahydro-2H-azepin-2-onato-N)magnesium could not be observed, but the substance decomposes at 216 °C.
