  • Chemische Eigenschaften Ammonium sulfide is a yellow crystalline (sugar or sand-like) material, commonly found in liquid solution, which is flammable. Solution has an odor of rotten eggs.
  • Chemische Eigenschaften yellow to orange fuming liquid
  • Chemische Eigenschaften The distinct ammonical/sulfurous odor of ammonium sulfide makes it a valuable flavor ingredient. It is used in baked goods, meat products, condiments and gravies.
  • Physikalische Eigenschaften Unstable, decomposes at ambient temperature; forms yellow crystals below -18°C; hygroscopic; soluble in water and alcohol, very soluble in liquid ammonia.
  • Verwenden Ammonium sulfide solution is used occasionally in photographic developing, to apply patina to bronze, and in textile manufacturing. Ammonium sulfide is a very useful reagent in mineral analysis. Used in continuous culture of saccharomyces cerevisiae, useful in a double staining technique for visualization of astrocytes and microglia from brain sections and astroglial cell cultures. It plays an important role to modify the surface of low κ dielectric thin films. It is essential for molecular beam epitaxy regrowth. It is an unstable salt and acts as a selective reducing agent.
  • Verwenden To apply patina to bronze, in photographic developers, in textile manufacture, in trace metal analysis.
  • Allgemeine Beschreibung Ammonium sulfide aqueous solution is a colorless to yellow liquid, with an odor of rotten eggs or ammonia. Material in aqueous from the hydrosulfide which with acid forms H2S. Ammonium sulfide may be irritating to skin, eyes and mucous membranes and may cause illness from skin absorption. Ammonium sulfide may burn and/or emit toxic fumes if heated to high temperatures.
  • Air & Water Reaktionen Readily oxidized to be pyrophoric in air [Bretherick 1979 p. 120]. Ammonium sulfide is slowly decomposed by moisture giving off hydrogen sulfide, a flammable gas. Heat is generated when the pure compound is first dissolved in water.
  • Reaktivität anzeigen AMMONIUM SULFIDE SOLUTION is a strongly alkaline aqueous solution. Reacts with acids to generate toxic gaseous hydrogen sulfide. Reacts with bases to release gaseous ammonia. May react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides. Special Hazards of Combustion Products: Toxic hydrogen sulfide gas is released when solution is heated. If ignited, this will form irritating sulfur dioxide gas [USCG, 1999].
  • Health Hazard Inhalation of 500 ppm for 30 min. produces headaches, dizziness, bronchial pneumonia; 600 ppm for 30 min. can cause death. Ingestion causes severe irritation of mucous membranes and stomach. Contact with liquid causes severe burns of eyes and severe skin irritation. May be absorbed through skin and cause hydrogen sulfide poisoning.
  • Brandgefahr Special Hazards of Combustion Products: Toxic hydrogen sulfide gas is released when solution is heated. If ignited, this will form irritating sulfur dioxide gas.
  • Industrielle Verwendung Ammonium sulfide (NH4)2S is a liquid with an obnoxious odor and because of this, it is not normally used in mineral processing. However, this is the most effective depressant for bornite and covellite. Essentially, (NH4)2S dissolves excess sulfur from the mineral surface, that allows other depressants to adsorb onto the mineral surface. In copper–lead separation, from a bulk concentrate containing covellite and bornite, (NH4)2S can effectively be used together with cyanide.
  • mögliche Exposition It is used in photographic developers, synthetic flavors, coloring metals (i.e., to apply patina to bronze); and to make textiles.
  • Versand/Shipping UN2923 Corrosive solids, toxic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poisonous material, Technical Name Required. UN2683 Ammonium sulfide solution, Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poisonous materials, 3-Flammable liquid
  • Inkompatibilitäten Vapor form explosive mixture with air Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Evolves poisonous ammonia on contact with strong bases. Contact with acid or acid fumes releases hydrogen sulfide. Keep away from moisture.
  • Waste disposal Add to a large volume of ferric chloride solution with stirring. Neutralize with soda ash. Flush to drain with water.
