化学的特性

Sodium nitrate, NaNO3, also known as soda niter and Chile saltpeter, is a fire-hazardous, transparent, colorless and odorless crystalline solid. It is soluble in glycerol and water,decomposes when heated,and melts at 308°C (585 °F). Sodium nitrate is used in making nitric and sulfuric acids, in the manufacture of glass and pottery enamel, as a fertilizer, as a food preservative, in explosives, and as a welding flux.

使用

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.

使用

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.

定義

ChEBI: The inorganic nitrate salt of sodium.

一般的な説明

A white crystalline solid. Noncombustible but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers, and for many other uses.

空気と水の反応

Soluble in water.

反応プロフィール

A mixture of Sodium nitrate and sodium hypophosphite constitute a powerful explosive [Mellor 8, Supp. 1:154 1964]. Sodium nitrate and aluminum powder mixtures have been reported to be explosive,[Fire, 1935, 28, 30]. The nitrate appears to be incompatible with barium thiocyanate, antimony, arsenic trioxide/iron(II) sulfate, boron phosphide, calcium-sodium alloy, magnesium, metal amidosulfates, metal cyanides, powdered charcoal, peroxyformic acid, phenol/trifluoroacetic acid, sodium, sodium nitrite/sodium sulfide, sodium phosphinate, sodium thiosulfate, tris( cyclopentadienyl)cerium, and even wood [Bretherick 5th ed., 1995].

危険性

Fire risk near organic materials, ignites on friction and explodes when shocked or heated to 1000F (537C). Toxic by ingestion; content in cured meats, fish, and other food products restricted.

健康ハザード

INGESTION: Dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, convulsions, and collapse. Small repeated doses may cause headache and mental impairment.

农业用途

Sodium nitrate is the oldest known nitrogenous fertilizer. It is a white, shiny crystal available in nature as Chilean saltpeter or Chilean nitrate.
Sodium nitrate is manufactured by two methods. In the first, known as the Guggenheim method, the fertilizer is extracted from a mined product, called caliche, mined mostly in Chile; hence the name (Chilean saltpeter or Chilean nitrate). The caliche is dissolved in warm water and then cooled to 0°C to produce sodium nitrate crystals, which are circulated through heat exchangers. The circulation keeps the crystals suspended, to finally form pellets. Caliche mined in Chile, contains sodium nitrate (8 to 20%), potassium and magnesium nitrates and salts like borates, sulphates and chlorides. Approximately, one ton of sodium nitrate of 99% purity is obtained from 10 tons of caliche. Sodium nitrate is shipped in airtight containers. The pellets are also coated to impart free-flowing characteristics.
Sodium nitrate is also manufactured from nitric acid and soda ash, using salt and oyster shells. Nitric acid is reacted with soda ash forming sodium nitrate solution. Most water is removed by evaporation and the rest is heated to a high temperature and sprayed through nozzles. Sodium nitrate solidifies as pellets while coming through the nozzles.
Sodium nitrate fertilizer is water-soluble. It contains 16% nitrogen and about 26% sodium. Plants absorb most of the nitrogen in a nitrate form and sodium nitrate is a commonly preferred fertilizer, although the nitrogen content of sodium nitrate is lesser than that in many other inorganic nitrogen fertilizers. Sodium nitrate has a neutralizing effect on soil acidity because of its inherent basic residual effect. Its neutralizing value is 0.82 kg of calcium carbonate equivalent to 0.45 kg of sodium nitrate.
The field crops which benefit most from sodium nitrate application are sugar beet and cotton. If applied excessively, sodium nitrate can damage the soil structure by reducing the flocculation. But normal applications of 100 to 200 kg of fertilizer/hectare/year do not affect the soil structure.

安全性プロファイル

Human poison by ingestion. Poison by intravenous route.Questionable carcinogen with experimental tumorigenic data. Human mutation data reported. A powerful oxidizer. It will iqte with heat or friction. Explodes when heated to over 1000°F, or when mixed with cyanides, sodium hypophosphte, boron phosphide. Forms explosive mixtures with aluminum powder, antimony powder, barium thiocyanate, metal amidosulfates, sodium, sodium phosphinate, sodium thiosulfate, sulfur + charcoal (gunpowder). Potentially violent reaction or ignition when mixed with bitumen, organic matter, calcium-shcon alloy, jute + magnesium chloride, magnesium, metal cyanides, nonmetals, peroxyformic acid, phenol + trifluoroacetic acid. Incompatible with acetic anhydride, barium thocyanate, wood. A dangerous disaster hazard. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx and Na2O. See also NITRATES.

純化方法

Crystallise NaNO3 from hot water (0.6mL/g) by cooling to 0o, or from a concentrated aqueous solution by adding MeOH. Dry it under a vacuum at 140o. After two recrystallisations, technical grade sodium nitrate had K, Mg, B, Fe Al, and Li at 100, 29, 0.6, 0.4, 0.2 and 0.2 ppm respectively. (See KNO3.)
