説明

Sodium carbonate is known as soda ash or washing soda and is a heavily used inorganic compound. Approximately 45 million tons of soda ash are produced globally both naturally and synthetically. Soda ash is obtained naturally primarily from the mineral trona, but it can also be obtained from nahcolite (NaHCO3) and salt brine deposits. Trona is a freshwater sodium carbonate-bicarbonate evaporite, with the formula Na3CO3HCO3 .2H2O. The largest known deposit of trona is located in the Green River area of Wyoming, and other large deposits are found in Egypt’s Nile Valley and California’s Searles basin around the city of Trona. Soda ash is produced from mined trona by crushing and screening the ore and then heating it. Th is produces a soda ash mixed with impurities. Pure soda ash is obtained by dissolving the product and precipitating impurities combined with filtering processes.

化学的特性

Sodium carbonate, Na2C03, also known as soda or soda ash,is the most important of the industrial alkalis. It is a white or grayish-white, lumpy, water-soluble powder that loses its water of crystallization when heated. It decomposes at a temperature of about 852°C (1560°F). It exists in solution only. It is prepared by the combination of carbon dioxide and water.

物理的性質

Carbonic acid has the formulaH2CO3 (equivalently OC(OH)2). It is also a name sometimes given to solutions of CO2 in water

来歴

Sodium carbonate, Na2CO3, has been used historically for making glass, soap, and gunpowder. Along with potassium carbonate, known as potash, sodium carbonate was the basis of the alkali industry, which was one of the first major chemical industries. Throughout history, alkalis were obtained from natural sources. Soda ash was also produced by burning wood and leaching the ashes with water to obtain a solution that yielded soda ash when the water was boiled off. The name soda ash originates from the barilla plant, which was used to produce soda ash. The scientific name of this plant is Salsola soda, but it goes by the common names of sodawort or glasswort because the soda produced from it was used in making glass. Barilla is a common plant found in saline waters along the Mediterranean Sea in Spain and Italy. Barilla was dried and burned to produce soda ash. The depletion of European forests and international disputes made the availability of alkali salts increasingly uncertain during the latter part of the 18th century. LeBlanc proposed a procedure in 1783, and a plant based on LeBlanc’s method was opened in 1791. Unfortunately, LeBlanc’s association with French Royalty led to the confi scation of the plant at the time of the French Revolution. Furthermore, confl icting claims for LeBlanc’s method were made by several other chemists and he never received the reward.

使用

Carbonic acid is used in the manufacture of soft drinks, inexpensive and artificially carbonated sparkling wines, and other bubbly drinks.

使用

Soda ash is used in glass making, in production of sodium chemicals (such as sodium chromates, phosphates, and silicates), in the wood pulp industry, in production of soaps and detergents, in oil refining, in water softening, and in refining of nonferrous metals. In its hydrous crystallized form (Na2C03.10H2O), it is known as sal soda,washing soda,or soda crystals, not to be confused with baking soda,which is sodium hydrogen carbonate or sodium bicarbonate (NaHC03). Its monohydrate form(Na2C03·H20) is the standard compound for scouring solutions.
When in solution, sodium carbonate creates less alkalinity than the hydroxides. A 0.1% solution creates a pH of 11;a fully saturated solution is 35%, which has a pH of 12.5.
The safety requirements for sodium carbonate, because of its lower alkalinity, can be considered less demanding than those for the related bicarbonates.

使用

Sodium Carbonate is an alkali that exists as crystals or crystalline powder and is readily soluble in water. it has numerous functions: an antioxidant, a curing and pickling agent, a flavoring agent, a processing aid, a sequestrant, and an agent for ph control. it is used in instant soups to neutralize acidity. it is used in alginate water des- sert gels to sequester the calcium, allowing the alginate to solubilize. it is also used in puddings, sauces, and baked goods.

使用

Sodium carbonate is also known as washing soda or carbonate of soda, sodium carbonate is a white crystal or powder made by converting salt into sodium sulfate, which was followed by roasting with limestone and coal. It is soluble in water and glycerin but not alcohol. Sodium carbonate was used as a pH modifier in toning baths and as the primary alkali in developers used for gelatin emulsions.

定義

A dibasic acid formed in small amounts in solution when carbon dioxide dissolves in water: CO2 + H2O?H2CO2 It forms two series of salts: hydrogencarbonates (HCO3–) and carbonates (CO32-). The pure acid cannot be isolated.

定義

carbonic acid: A dibasic acid,H2CO3, formed in solution when carbondioxide is dissolved in water:
CO2(aq) + H2O(l) →H2CO3(aq)
The acid is in equilibrium with dissolvedcarbon dioxide, and also dissociatesas follows:
H2CO3→H+ + HCO3-
Ka = 4.5 × 10–7 mol dm–3
HCO3→CO32–+ H+
Ka = 4.8 × 10–11 mol dm–3
The pure acid cannot be isolated,although it can be produced in ethersolution at –30°C. Carbonic acid givesrise to two series of salts: the carbonatesand the hydrogencarbonates.

定義

sodium carbonate: Anhydrous sodium carbonate (soda ash, sal soda) is a white powder, which cakes and aggregates on exposure to air due to the formation of hydrates. The monohydrate, Na2COH2O, is a white crystalline material, which is soluble in water and insoluble in alcohol; r.d. 2.532; loses water at 109°C; m.p. 851°C.
The decahydrate, Na2CO3·10H2O (washing soda), is a translucent efÛorescent crystalline solid; r.d. 1.44; loses water at 32–34°C to give the monohydrate; m.p. 851°C.
Sodium carbonate may be manufactured by the Solvay process or by suitable crystallization procedures from any one of a number of natural deposits, such as:
trona (Na2CO3·NaHCO3·2H2O),
natron (Na2CO3·10H2O),
ranksite (2Na2CO3·9Na2SO4·KCl),
pirsonnite (Na2CO3·CaCO3·2H2O),
gaylussite (Na2CO3·CaCO3·5H2O).
The method of extraction is very sensitive to the relative energy costs and transport costs in the region involved. Sodium carbonate is used in photography, in cleaning, in pH control of water, in textile treatment, glasses and glazes, and as a food additive and volumetric reagent.

安全性プロファイル

Poison by intraperitoneal route. Moderately toxic by inhalation and subcutaneous routes. Mlldly toxic by ingestion. Experimental reproductive effects. A skin and eye irritant. It migrates to food from packagmg materials. Can react violently with Al, P2O5, H2SO4, F2, Li, 2,4,6-trinitrotoluene. When heated to decomposition it emits toxic fumes of Na2O

純化方法

It crystallises from water as the decahydrate which is redissolved in water to give a near-saturated solution. By bubbling CO2, NaHCO3 is precipitated. It is filtered off, washed and ignited for 2hours at 280o [MacLaren & Swinehart J Am Chem Soc 73 1822 1951]. Before being used as a volumetric standard, analytical grade material should be dried by heating at 260-270o for 0.5hour and allowed to cool in a desiccator. It has a transition point at 450o, and its solubility in water is 21.58% at 20o (decahydrate in solid phase), 49.25% at 35o (heptahydrate in solid phase) and 44.88% at 75o(monohydrate in solid phase) [D.nges in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 987-988 1963]. After three recrystallisations, technical grade Na2CO3 had Cr, Mg, K, P, Al, W, Sc and Ti at 32, 9.4, 6.6, 3.6, 2.4, 0.6, 0.2 and 0.2 ppm respectively; another technical source had Cr, Mg, Mo, P, Si, Sn and Ti at 2.6, 0.4, 4.2, 13.4, 32, 0.6, 0.8 ppm respectively.
