Ammonium azide acid with ammonia

Earlier, Turrentine (Ref 4) obtained ferric azide in soln by electrolysis of a dil sodium azide soln using iron electrodes and later by Browne et al (Ref 6) on using iron electrodes in liq amm solns of ammonium azide, but the product was ammonolyzed to an Ammono-Basic Ferric Azide. Curtius et al (Refs 1 2), with ferric alum and NaN, obtained ferric azide in soln and they also repotted that iron dissolved in dil aq hydrazoic acid to form the azide, but the soln decompd on evapn giving either the basic azide or hydroxide. In 1934 Franklin (Ref 9) noted that aq hydrazoic acid reacts on iron to form ferric azide, nitrogen and ammonia together with a small amt of hydrazine. According to Franklin Ferrous Azide, Fe(Nj), is formed first and oxidizes to ferric azide when the soln is warmed with excess hydrazoic acid present. Ricca (Ref 11) studied the reactions of the ferric ion with hydrazoic acid on electrolysis of their solns and obtained results which would indicate that ferric azide has the structure [Fe(Nj)](Nj)2... 

The preparation of ammonium azide by the interaction of ammonia with hydrazoic acid in ethereal solution has been described by Frierson. A second preparative method using ammonium nitrate or sulfate is also described in the same reference. Both methods have disadvantages, in that the former requires the preparation of hydrazoic acid, whereas the latter is limited to small quantities because of explosion hazards. 

Two German patents by Muller describe preparative methods which avoid the use of hydrazoic acid by heating sodium azide with ammonium chloride or sulfate in aqueous solution. A recent Japanese patent describes a reaction between sodium azide and ammonium carbamate in liquid ammonia to give ammonium azide. Evans, Yoffe, and Gray have suggested the reaction of sodium azide with ammonium chloride in iV,iV-dimethylformamide. A modification of the last method has been made it involves the reaction of sodium azide and ammonium sulfate in dimethyl-formamide to give anhydrous ammonium azide of high purity. 

COPPER (7440-50-8) Cu The powder forms the friction-, heat-, or shock-sensitive explosive detonator, copper acetylide, with acetylene gas acetylenic compounds and ethylene oxides. The powder forms explosive materials with azides (e.g., sodium azide forms potentially explosive copper azide). Finely divided material forms friction-, heat-, or shock-sensitive explosive with powdered divided bromates, chlorates, and iodates of barimn, calcimn, magnesium, potassium, sodium, or zinc. Violent reaction, possibly explosive, when finely dispersed powder comes in contact with strong oxidizers ammonium nitrate alkynes, bromine vapor, calcium carbide, chlorine, ethylene oxide, hydrazine mononitrate, hydrogen peroxide, hydrogen sulfide, finely divided bromates, iodine, lead azide, potassium peroxide, sodium peroxide (incandescence), sulfuric acid. Incompatible with acids, anhydrous ammonia chemically active metals such as potassium, sodium, magnesium, and zinc, zirconium, strong bases. 

DIMETHYL ESTER of SULFURIC ACID (77-78-1) Combustible liquid (flash point 182°F/83°C). Violent reaction with strong oxidizers, strong acids, strong alkalis, ammonia, ammonium hydroxide, barium chlorite, sodium azide. Incompatible with strong ammonia solutions. Attacks some plastics, rubber, and coatings.
