Oxygen-based explosives I know that oxidanes are oxygen chains and rings. For example trioxidane is $\ce{HO-O-OH}$. I can see this turning into $\ce{O2}$ and $\ce{H2O}$ like hydrogen peroxide does. Since the double bonds in $\ce{O2}$ are strong do oxygen compounds without nitrogen ever explode?
They do indeed explode. Oxyliquits are probably the most comprehensive example of liquid-oxygen-based primary explosives (which are considered obsolete today). Theoretically liquid oxygen can also be substituted with ozone-oxygen mixture, which in reality has never been utilized due to technical difficulties -- oxyliquits were popular in the beginning of 20th century.
