Decomposition of hydrazoic acid in nitric acid

Abstract
Hydrazoic acid in solution in nitric acid at 97 °C decomposes to form a mixture of N2, N2O, and NO. The reaction is strongly acid catalysed and the kinetics of decomposition are first order with respect to hydrazoic acid concentration. The mechanism proposed involves electrophilic attack by NO2+ on hydrazoic acid to form N3ONO, which can then fragment to N2+ 2NO˙ or dissociate to N3˙+ NO2˙. Dinitrogen monoxide is thought to arise from the reaction sequence: 2NO2˙→ N2O4; N2O4+ HN3→ N3NO + HNO3; N3NO → N2+ N2O.
