Nitrate as oxidant

In the oxidation of hydroxylamine by silver salts and mercurous salts, the nature of the reaction product apparently depends upon the extent to which catalysis participates in the total reaction. This is illustrated by some results obtained with mercurous nitrate as oxidizing agent. The reaction is strongly catalyzed by colloidal silver, and is likewise catalyzed by mercury. The reaction of 0.005 M mercurous nitrate with 0.04 M hydroxylamine at pH 4.85 proceeds rapidly without induction period. The mercury formed collects at the bottom of the vessel in the form of globules when no protective colloid is present, so the surface available for catalysis is small. Under these conditions the yield is largely nitrous oxide. Addition of colloidal silver accelerates the reaction and increases the yield of nitrogen. Some data are given in Table III. 

Phillips Petroleum in the United States [23] developed a propellant composed of ammonium nitrate as oxidant and rubber as a combustible and binding agent. The rubber consists of synthetic rubber and such typical rubber ingredients as carbon black (to improve the mechanical properties of rubber), an accelerator and an inhibitor (to prevent oxidation). To endow the rubber with sufficient plasticity...

The use of molten nitrates as oxidants for nuclear fuel components has not been studied as much as other pyrochemical or pyrometallurgical processes. Previous studies of molten nitrate systems were primarily conducted in European laboratories, although some research was done in Japan and the United States. 

Fusion or Roast Technique for Hard Scrap [5.27-5.29]. Fusion is performed at high temperature with sodium nitrite or sodium nitrate as oxidizing agent and sodium carbonate as dilutant and must be carefiilly controlled. Roasting is done in rotary kilns at 800 °C using a 1 3 mixture of oxidizer and diluent After cooling, the cake must be crushed prior to dissolution in water. 

Aminoanthraquinone from 2-Chloroanthraquinone. By the use of potassium chlorate and ammonium nitrate as oxidants, it is possible to obtain directly a 2-amino-anthraquinone of 97.5-98.5 per cent purity. A copper catalyst is not essential but is sometimes used to moderate the conditions of the reaction. The only treatment required is a thorough washing of the 2-aminoanthraquinone with hot dilute aqueous ammonia or dilute sodium hydroxide. 

Others have used a high-temperature (500°C) ashing technique that includes magnesium sulphate or magnesium nitrate as oxidant (Soldrzano and Sharp, 1980 ... 

Although the earliest explosive was gunpowder (black powder), consisting of sulfur, potassium nitrate (as oxidizing agent) and charcoal, it was the discovery of nitroglycerine (in 1847), of trinitrotoluene (TNT, in 1863) and of dynamite (made in... 

Several groups of bacteria can use hydrogen sulfide as fuel, oxidizing it to elemental sulfur or to sulfate by using dissolved oxygen, metal oxides (e g., Fe oxyhydroxides and Mn oxides) or nitrate as oxidant.
