• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. Ingestion could cause effects on the blood. This may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.
• Uses: Sodium nitrate is one of the earliest nitrogen fertilizer, can be used for acid soil, especially suitable for root crops, such as sugar beet and radish. In the end of the 19th century to the early 20th century, Chile exploited sodium nitrate mining in large scale as nitrogen fertilizer for the world. Farmers in Xinjiang uygur autonomous region in China digged desert surface soil contain NaNO3 to plant grape fruits, and the fertilizer effect is remarkable. Sodium nitrate can be used to make nitrate, picric acid, explosives, mineral raw materials, dyes, osmotic pressure regulator in medicine and other nitrogen compounds, it also can be used in glass, metallurgy, light industry and other industrial sectors. In glass industry, it can be used for the production of various kinds of glass and its products of defoaming agent, decoloring agent, clarifying agent and oxidation solubilizer. Enamel industry uses it as oxidant, solubilizer, and to make enamel powder. Machinery industry uses it as metal cleaner, dispensing black metallic blue agent. Metallurgical industry uses it for steel and aluminum alloy heat treatment. Light industry uses it as combustion improver of cigarettes. Pharmaceutical industry uses it as a medium of penicillin. It can be reduction by bacteria into sodium nitrite in meat, which results in color protection and bacteriostatic effect, and can be used as food color fixative in China. It also can be used as decolorizing agent of molten caustic soda and analytical reagent. Sodium Nitrate is the salt of nitric acid that functions as an antimi- crobial agent and preservative. it is a naturally occurring substance in spinach, beets, broccoli, and other vegetables. it consists of color- less, odorless crystals or crystalline granules. it is moderately deli- quescent in moist air and is readily soluble in water. it is used in meat curing to develop and stabilize the pink color. see nitrate. In manufacturing of HNO{3}, as a catalyst to manufacture H{2}SO{4}, in manufacturing of glass, enamel for pottery, sodium nitriteSodium nitrate is used in the production of fertilizers, nitric acid, pyrotechnics, smoke-bombs, glass and pottery enamels. In combination with boron trifluoride it forms an efficient reagent for nitration of aromatic compounds. Adsorption on alumina provides an environmentally benign aromatic nitrating agent. Further it finds use as food preservative and as a solid rocket propellant. It is also used as an electrolyte in a salt bridge, and as thermal storage medium in power generation systems. manufacture of nitric acid and as catalyst in the manufacture of sulfuric acid. manufacture of sodium nitrite, glass, enamels for pottery; in matches; for improving burning properties of tobacco; pickling meats; as color fixative in meats. Clinical reagent (parasites). The technical grade is used as fertilizer.
• Production Method: Absorption method: Bubble the exhaust derived from nitric acid production (contain NO + NO2 0.5%~1.5%) into the bottom of absorption tower, use soda solution with a relative density of 1.240~1.3 and temperature of 25~60 oC spraying from the top of the tower to absorption nitrous oxide in gas, and then obtain the neutralizer. Add neutralizing liquid and nitric acid into converter, sodium nitrite will transform into sodium nitrate, the conversion temperature is between 90~105 oC, stirring with air at the same time. Using soda solution to neutralize the free acid in converted solution, keeping the alkalinity below 0.3 g/L, in atmospheric evaporation to solution the boiling point of 123~123 oC, through cooling crystallization, centrifugal separation, drying, sodium nitrate is obtained. Na2CO3+NO+NO2→2NaNO2+CO2↑ Na2CO3+2NO2→NaNO2+NaNO3+CO2↑ 3NaNO2+2HNO3→3NaNO3+H2O+2NO↑ Nitrogen gas released from oxidation reaction process can be returned to nitric acid production system to make nitric acid. Double decomposition method: Mix 50%~52% of calcium nitrate, sodium sulfate and calcium nitrate solution cycle solution into a stirring reactor, reaction was conducted in the 50~55 oC under stirring for 3~4 h, filter the plaster through vacuum filter, and further filter to remove impurities, remove plaster after been washed with water, wash water merged with the filtrate, part of them return to diluted slurry reactor, and part of them been evaporation and concentration, through cooling crystallization, centrifugal separation and drying, sodium nitrate is obtained. Ca(NO3)2+Na2SO4→2NaNO3+CaSO4↓ Direct extraction method: The sodium nitrate ore is broken to a certain size, use fresh water or brine to spray heap leaching, then get a certain concentration of sodium nitrate brine, cooling to separate mirabilite, send brine to evaporation pans tan, until sodium nitrate alum (Na2SO4, NaNO3·H2O) crystal appeared, after filtering, the by-produc of sodium chloride brine continue insolation evaporation to get semi-finished products contained sodium nitrate alum. Melt the semi-finished product with a certain amount of brine (or crystallization mother liquor), after been filtered to remove impurities, filtrated the cooling crystallization, centrifugal separation, drying, sodium nitrate is obtained. Conversion method: Sodium nitrite concentration and dilute nitric acid mother liquor are sent into the tower, through steam heating and ventilation with compressed air mixing, then transform into sodium nitrate solution, add soda solution until slightly alkaline solution, then through purification, filtration, removal of arsenic and heavy metals, evaporation and concentration, cooling crystallization, centrifugal separation, drying, the food grade sodium nitrate is obtained. 3NaNO2+2HNO3→3NaNO3+H2O+2NO↑
• Description: Sodium nitrate, also known as Chile saltpeter and soda niter, has a molecular formula of NaNO3. Sodium nitrate is a colorless, odorless, transparent crystal. It oxidizes when exposed to air and is soluble in water. This material explodes at 1000°F (537°C), much lower than temperatures encountered in many fires. Sodium nitrate is toxic by ingestion and has caused cancer in test animals. When used in the curing of fish and meat products, it is restricted to 100 ppm. Sodium nitrate is incompatible with ammonium nitrate and other ammonium salts. The four-digit UN identification number is 1498. Sodium nitrate is used as an antidote for cyanide poisoning and in the curing of fish and meat.
