Sodium Azide → Pentanitrophenyl azide

Participants

Reaction Steps

The reaction is conducted by stirring a benzene solution of hexanitrobenzene with a slight excess of sodium azide (aqueous solution) at 25° C. After separating and drying the benzene solution, the solvent is removed leaving pure pentanitrophenyl azide. Recrystallization from carbon tetrachloride gives either long, flat yellow prisms (α-form) or chunky, orange-yellow rosettes (β-form) of pentanitrophenyl azide.
