  • Beschreibung Potassium sulfate (K2SO4) is a kind of chemical compounds that is commonly used in agriculture. The dominant application of potassium sulfate is as a fertilizer, which is commonly applied to offer both potassium and sulfur, thus improving the quality and yield of crops growing in soils that lack an adequate supply of this essential elements. Besides, the crude potassium sulfate is sometimes employed in the production of glass. It also has applications in other industries, which is used as a flash reducer in artillery propellant charges and as an alternative blast media similar to soda in the process of soda blasting.

  • Chemische Eigenschaften Potassium sulfate,K2804, also known as salt of Lemery and arcanite, is a colorless crystalline solid that melts at 1072°C(1960 OF). It is soluble in water,but insoluble in alcohol. Potassium sulfate is used in manufacturing glass, aluminum, fertilizers, and in medicine.
  • Chemische Eigenschaften Potassium sulfate, sulfate of potash, K2SO4, white solid, soluble. Common constituent of potassium salt minerals.
  • Physikalische Eigenschaften Colorless or white crystals or white granules or powder; rhombohedral structure; bitter taste; density 2.66 g/cm3; melts at 1,069°C; vaporizes at 1,689°C; moderately soluble in water, 12 g/100mL at 25°C and 24g/100mL at 100°C; slightly soluble in glycerol; insoluble in alcohol, acetone, and carbon disulfide.
  • Occurrence Potassium and sodium sulfates and their double sulfates with calcium and magnesium occur naturally in various salt lakes. Potassium sulfate also occurs in certain volcanic lava. Its double salt with magnesium occurs in nature, as the mineral langbeinite.
    Potassium sulfate is used in fertilizers as a source of potassium and sulfur, both of which are essential elements for plant growth. Either in sim-ple form or as a double salt with magnesium sulfate, potassium sulfate is one of the most widely consumed potassium salts in agricultural applications. It is preferred over potassium chloride for certain types of crops; such as, tobac-co, citrus, and other chloride-sensitive crops. Some other applications include making gypsum cements; to make potassium alum; in the analysis of Kjeldahl nitrogen; and in medicine.
  • Verwenden Potassium Sulfate is a flavoring agent that occurs naturally, consisting of colorless or white crystals or crystalline powder having a bitter, saline taste. it is prepared by the neutralization of sulfuric acid with potassium hydroxide or potassium carbonate.
  • Verwenden Technical grades are used in fertilizers for manufacture of potassium alum, potassium carbonate and glass; the reagent grade is used in the Kjeldahl determination of nitrogen.
  • Verwenden potassium sulfate is a reagent in cosmetics. Potassium sulfate is an inorganic salt with a primary function as a viscosity-increasing agent.
  • Definition A white crystallinepowder, K2SO4, soluble inwater and insoluble in ethanol;rhombic or hexagonal; r.d. 2.66; m.p.1069°C. It occurs naturally assch?nite (Strassfurt deposits) and inlake brines, from which it is separatedby fractional crystallization. Ithas also been produced by the Hargreavesprocess, which involves theoxidation of potassium chloride withsulphuric acid. In the laboratory itmay be obtained by the reaction ofeither potassium hydroxide or potassiumcarbonate with sulphuric acid.Potassium sulphate is used in cements,in glass manufacture, as afood additive, and as a fertilizer(source of K+) for chloride-sensitiveplants, such as tobacco and citrus.
  • Vorbereitung Methode Potassium sulfate is produced by various methods, selection of process depending on availability and cost of raw materials.
    The salt may be obtained from its naturally occurring mineral, langbeinite,K2SO4?2MgSO4. The ore first is crushed and washed with water to separate sodium chloride. After that, magnetite is separated from the washed langbei-nite by magnetic separation. After the separation of these two major impuri-ties, the purified double salt is treated with an aqueous solution of potassium chloride to obtain potassium sulfate:
    K2SO4?2MgSO4 + 4KCl →3K2SO4+ 2MgCl2
    The solution is filtered to remove insoluble residues and the products are separated from their aqueous mixture by crystallization.
    Potassium sulfate also is produced from the mineral kieserite, MgSO4?H2O by treatment with potassium chloride. The intermediate double salt obtained reacts further with potassium chloride to form potassium sulfate:MgSO4?H2O + 2KCl + 4H2O →K2SO4?MgSO4?6H2O + MgCl2
    K2SO4?MgSO4?6H2O + 2KCl →2K2SO4+ MgCl2
    Potassium sulfate is separated from the more soluble magnesium chloride by crystallization.
    Also, potassium sulfate can be made by two other processes in which no naturally occurring mineral is employed. In the Mannheim process, the salt is produced by action of sulfuric acid on potassium chloride:2KCl + H2SO4→K2SO4+ 2HCl
    In Hargreaves process, which is a slight variation of the Mannheim method, potassium sulfate is made by heating a mixture of potassium chlo-ride, sulfur dioxide, air and water:4KCl + 2SO2+ 2H2O + o2→2K2SO4+ 4HCl.
  • Sicherheitsprofil Moderately toxic to humans by ingestion. Moderately toxic experimentally by subcutaneous route. Swallowing large doses causes severe gastrointestinal tract effects. When heated to decomposition it emits toxic fumes of K2O and SOx. See also SULFATES.
