Nitrolysis is a chemical reaction involving cleavage ("lysis") of a chemical bond concomitant with installation of a nitro group (NO2). Typical reagents for effecting this conversion are nitric acid and acetyl nitrate. A commercially important nitrolysis reaction is the conversion of hexamethylenetetramine to the nitramide (O2NNCH2)3. Called RDX, this trinitramide is a widely used explosive.
