Product: Sodium nitrate Standard: GB/T 4553-2002 Molecular formula: NaNO3 Molecular weight: 84.99 |  |
Properties
Colorless diamond crystal or white fine crystalline powder，No odor, salty taste, slightly bitter. Soluble in water and ammonia, dissolved in ethanol, methanol, slightly soluble in glycerol and acetone. Exposure to organic compounds, sulfur will lead to combustion and explosion. Sodium Nitrate is a highly water soluble crystalline Sodium source for uses compatible with nitrates and lower (acidic) pH. All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion. The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Formula: NO3) for a total formula weight of 62.05. Nitrate compounds are generally soluble in water. Nitrate materials are also oxidizing agents. When mixed with hydrocarbons, nitrate compounds can form a flammable mixture. Nitrates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials. Sodium Nitrate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.
The industrial synthesis of sodium nitrate involves the neutralization of nitric acid with sodium carbonate, sodium bicarbonate, or sodium hydroxide. The chemical equations for these reactions are listed below.
NaHCO3 + HNO3 → NaNO3 + H2O + CO2
Na2CO3 + 2HNO3 → 2NaNO3 + CO2 + H2O
NaOH + HNO3 → NaNO3 + H2O
It is important to note that the reaction between sodium hydroxide and nitric acid is a highly exothermic one (since NaOH is a strong base and HNO3 is a strong acid). Therefore, an alternate method of preparing sodium nitrate is by reacting sodium hydroxide with ammonium nitrate instead of nitric acid. The chemical reaction is:
NH4NO3 + NaOH → NH4OH + NaNO3
Alternately, ammonium nitrate can be reacted with sodium carbonate or sodium bicarbonate.
Na2CO3 + 2NH4NO3 → (NH4)2CO3 + 2NaNO3
NaHCO3 + NH4NO3 → NH4HCO3 + NaNO3
Applications
Raw material of making potassium nitrate, mining explosives, picric acid, dyes. nitrating agent of dye intermediates. Glass industry as defoamer, bleaching agent, clarifying agent and oxidizing flux.Meat processing used as hair coloring agent, can also be used as anti-microbial agents, preservatives.
