  • Chemische Eigenschaften Sodium sulfate, NaS04, also known as thenardite and salt cake, is a crystalline compound that melts at 888°C (1632°C). Sodium sulfate is found in natural form(thenardite) in Chile and Spain. It is used in the manufacture of paperboard, glass,and freezing mixtures. The hydrate, Na2S04·10H20, also known as "Glauber's salt," is a white water-soluble solid formed by heating sodium chloride and sulfuric acid. It is used in dyeing,manufacturing glass,and in the preparation of sodium bisulfate.
  • Chemische Eigenschaften Sodium sulfate is a white crystalline solid. It frequently is found as the decahydrate
  • Verwenden sodium sulfate is a filler in the manufacturing of synthetic detergents and soaps and a laboratory reagent. It may enhance the irritant action of certain detergents.
  • Verwenden Used in kjeldahl nitrogen determination; drying agent .
  • Verwenden Sodium Sulfate is the salt of sulfuric acid that is readily soluble in water and exists as crystals or crystalline powder. it is used in cara- mel production.
  • Definition A white crystalline compound, Na2SO4, usually known as the anhydrous compound (orthorhombic; r.d. 2.67; m.p. 888°C) or the decahydrate (monoclinic; r.d. 1.46; which loses water at 100°C). The decahydrate is known as Glauber’s salt. A metastable heptahydrate (Na2SO4·7H2O) also exists. All forms are soluble in water, dissolving to give a neutral solution. The compound occurs naturally as
    mirabilite (Na2SO10H2O),
    threnardite (Na2SO4), and
    glauberite (Na2SO4·CaSO4).
    Sodium sulphate may be produced industrially by the reaction of magnesium sulphate with sodium chloride in solution followed by crystallization, or by the reaction of concentrated sulphuric acid with solid sodium chloride. The latter method was used in the Leblanc process for the production of alkali and has given the name salt cake to impure industrial sodium sulphate. Sodium sulphate is used in the manufacture of glass and soft glazes and in dyeing to promote an even finish. It also finds medicinal application as a purgative and in commercial aperient salts.
  • Sicherheitsprofil Moderately toxic by intravenous route. Mildly toxic by ingestion. An experimental teratogen. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic effects. Violent reaction with Al. When heated to decomposition it emits toxic fumes of SOx and Na2O. See also SULFATES.
  • mögliche Exposition Sodium sulfate is used in the manufacture of glass; as a precipitating agent in the manufacture of silver emulsions; as an analytical reagent; in making ultramarine and paper pulp; in ceramic glazes and pharmaceuticals; as a food additive; and a filler in synthetic detergents.
  • Veterinary Drugs and Treatments Sodium sulfate is used as a saline cathartic, primarily in food animals.
  • Versand/Shipping UN2630 Selenates or Selenites, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
  • läuterung methode Crystallise sodium sulfate from water at 30o (1.1mL/g) by cooling to 0o. It becomes anhydrous at 32o.
  • Inkompatibilitäten Violent reaction with aluminum, magnesium. Attacks metals in the presence of moisture.
  • Waste disposal Do not discharge waste sodium sulfate directly into sewers or surface waters. Recovered sodium sulfate may be disposed of by burial in a landfill.
