  • Beschreibung Potassium carbonate is a white, crystalline, salt that forms basic aqueous solutions used in the production of fertilizer, glass, ceramics, explosives, soaps, chemicals, and wool treatments. It was the main compound once referred to as potash, although the term today is not reserved exclusively for potassium carbonate, but for several potassium salts. In the fertilizer industry potash refers to potassium oxide, K2O, rather than potassium carbonate.Pearlash is a purer form of potash made by heating potash to remove impurities.
  • Chemische Eigenschaften white powder or granules
  • Verwenden It is used as drying agent for organic solvents; a base.
  • Verwenden Potassium Carbonate is a general purpose food additive and alkali. it is hygroscopic and the aqueous solutions are strongly alkaline. it has a solubility of 1 g in 1 ml of water at 25°c. it is used as a flavoring agent and processing aid, and to control ph. it is used in soups to neutralize acidity.
  • Verwenden Potassium carbonate is used for numerous applications. Its primary use is in the production of specialty glasses and ceramics. It is used to make optical glass, glass used for video screens in televisions and computers, and laboratory glassware. Its is used in certain glasses rather then cheaper sodium carbonate owing to its better compatibility with lead, barium, and strontium oxides incorporated in these glasses. These oxides lower the melting point of glass and produce a softer glass. Potassium carbonate has a higher refractive index than sodium carbonate producing a more brilliant glass. Potassium carbonate is a common flux combined with titanium dioxide to produce frits used in ceramics. A frit is a calcined mixture of fine silica, a pigment, and a flux that is ground a specific particle size and used to produce glazes, enamels, and additives in glass making.
    Potassium carbonate is used in agriculture and food production. Potassium carbonate is used as a spray or drip fertilizer and also as a constituent of compound fertilizers. Its high water solubility and alkaline property make it useful for supplying potassium to acidic soils, especially in vineyards and orchards. Dutch-processed cocoa uses potassium carbonate as an alkalizing agent to neutralize the natural acidity of cocoa. It is used to produce food additives like potassium sorbate and monopotassium phosphate.
    Potassium carbonate is used in the chemical industry as a source of inorganic potassium salts (potassium silicates, potassium bicarbonate), which are used in fertilizers, soaps, adhesives, dehydrating agents, dyes, and pharmaceuticals. Potassium carbonate used to make potassium lye produces soft soaps, which are liquids or semisolids rather than solids. Other uses of potassium carbonate includes use as a fire suppressant in extinguishers, as a CO2 absorbent for chemical processes and pollution control, an antioxidant in rubber additives, and in pharmaceutical formulations.
  • Definition ChEBI: A potassium salt that is the dipotassium salt of carbonic acid.
  • Vorbereitung Methode The name potash comes fromthe traditional method of making potassium carbonate, which has been performed sinceancient times. Preparing potassium carbonate involved burning wood or other plant material,leaching the ashes in a wooden barrel covered on its bottom with straw, and then evaporatingor boiling away the water in the leachate in clay or iron pots to recover potassium and sodiumalkalis.
  • Allgemeine Beschreibung An aqueous solution of potassium hydroxide. Corrosive to metals and tissue. Density 12.8 lb /gal. Used to make soaps, other potassium compounds, in liquid fertilizers.
  • Air & Water Reaktionen Water soluble. Addition of water evolves heat.
  • Reaktivität anzeigen Potassium carbonate neutralizes acids exothermically to form salts plus water. Reacts with certain metals (such as aluminum and zinc) to form oxides or hydroxides of the metal and generate gaseous hydrogen. May initiate polymerization reactions in polymerizable organic compounds, especially epoxides. May generate flammable and/or toxic gases with ammonium salts, nitrides, halogenated organics, various metals, peroxides, and hydroperoxides. May serve as a catalyst. Reacts when heated above about 84°C with aqueous solutions of reducing sugars other than sucrose, to evolve toxic levels of carbon monoxide [Bretherick, 5th Ed., 1995].
  • Hazard Solutions irritating to tissue.
  • Health Hazard TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
  • Brandgefahr Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
  • Landwirtschaftliche Anwendung Potassium carbonate (K2C03) in solution form can be used as a liquid fertilizer. A limited quantity of the solid is used as a non-chloride form of potassium for tobacco.
    Potassium carbonate is obtained from ash. It is made by electrolysis of potassium chloride. Potassium hydroxide on reaction with carbon dioxide gives potassium carbonate. Liquid carbonate contains about 50% potassium carbonate in water. The solid product, which contains over 70% potassium carbonate is fairly expensive and is of use in only limited types of acid soil. Neutralizing caustic potash with carbon dioxide gas also produces potassium carbonate.
  • Landwirtschaftliche Anwendung The term potash designates potassium oxide (K2O). Potassium oxide is never used as such in fertilizers. The term potash is loosely applied to potassium salts, but it generally refers to potassium carbonate (K2C03), or potassium chloride (KCl). Potash in fertilizers is usually present in the form of a muriate or sulphate, and occasionally in the form of a carbonate or nitrate.
    The ores of naturally occurring potassium salts are called potash ores. Low-grade potash materials are kainite, basalt, sylvinite, carnalite and schoenite. The potassium content of fertilizers is expressed as percent potash (K2O)
  • Sicherheitsprofil Poison by ingestion. A strong caustic. Incompatible with KCO, chlorine trifluoride, magnesium. Mutation data reported. When heated to decomposition it emits toxic fumes of K2O.
  • läuterung methode It crystallises from water between 100o and 0o. The solubility in H2O is 105% at 0o, 127% at 60o and 205% at 135o (b of saturated solution). After two recrystallisations of technical grade material, it had B, Li and Fe at 1.0, 0.04 and 0.01 ppm, respectvely. [D.nges in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 987 1963.]
