Acetone Peroxide (AP), also called peroxyacetone, is a powerful explosive. It was discovered in 1895 by R. Wolffenstein (Chemische Berichte 28, 2265 (1895). Acetone peroxide is probably the simplest explosive to make because the materials for it are readily available. It can be made from household items such as sulphuric acid (often drain cleaner), hydrogen peroxide and acetone. The acetone peroxides contained in oxidate reaction mixtures thereof, for instance, those resulting from phenol syntheses, are hazardous and explosive compounds when present in the solid state, and are consumed by adjusting the pH of such reaction mixture to a value ranging from 4 to 8, adding a copper compound to such reaction mixture, and maintaining such reaction mixture at a temperature ranging from 50° C. to 150° C.
