Beryllium azide is an inorganic chemical compound of beryllium from the group of azides .

Extraction and presentation

Beryllium azide can be prepared by reaction of Berylliumdimethyl with hydrazoic acid are obtained at temperatures below -116 ° C.

${\displaystyle \mathrm {Be(CH_{3})_{2}+2\ HN_{3}\longrightarrow Be(N_{3})_{2}+2\ CH_{4}} }$

Alternatively, it can be obtained by reacting beryllium chloride with trimethylsilyl azide .

${\displaystyle \mathrm {BeCl_{2}+2\ (CH_{3})_{3}SiN_{3}} }$ ${\displaystyle \mathrm {\longrightarrow Be(N_{3})_{2}+2\ (CH_{3})_{3}SiCl} }$

properties

Beryllium azide is a colorless solid that evaporates when ignited. It is not sensitive to impact and will weather quickly in moist air. Hydrolytic decomposition occurs in aqueous solution.
