Dinol - Diazodinitrophenol

In more recent years there has been the development of lead-free primers based on the organic shock-sensitive initiator dinol (diazodinitrophenol) in place of the lead styphnate. Commercial formulations of dinoTbased primer have been developed which include mixtures such as dinol, zinc peroxide, metallic titanium, and tetrazene dinol, manganese(IV) oxide, and metallic aluminum and dinol, antimony sulfide, and barium nitrate. 

Diazodinitrophenol (DDNP or Dinol) [Structure (2.11)] or 4,6-dinitrobenzene-2-diazo-l-oxide was first prepared by Griess [9] in 1858 but was developed commercially as a detonating agent 70 years later. It is prepared by the diazotization of...

Diazodinitrophenol (DDNP, Dinol) 4,6-Dinitrobenzene-2-diazo-l-oxide, or diazodinitrophenol as it is more commonly called, occupies a place of some importance in the history of chemistry, for its discovery by Griess56 led him to undertake his classic researches on the diazonium compounds and the diazo reaction. He prepared it by passing nitrous gas into an alcoholic solution of picramic acid, but it is more conveniently prepared by carrying out the diazotization in aqueous solution with sodium nitrite and hydrochloric acid.
