• Chemische Eigenschaften

  Ammonium bicarbonate is a white crystalline solid with a faint ammonia odor and soluble in water but insoluble in alcohol and acetone. It decomposes above 35℃ to ammonia, carbon dioxide and water vapor, releasing irritant fumes. Only 30% of the applied nitrogen of this fertilizer is recovered by plants owing to the unstable nature of ammonium bicarbonate. that forms by the reaction of anunonium hydroxide and excess CO2.

• Physikalische Eigenschaften

  White crystalline solid; prismatic crystal; faint odor of ammonia; stable at ambient temperature but decomposes on heating at 60°C; melts at 107.5°C on very rapid heating; density 1.586 g/cm³; vapor pressure 435 torr at 25°C; readily dissolves in water (21.6g/100g at 20°C, and 36.6g/100g at 40°C).

• Verwenden

  Ammonium Bicarbonate is a dough strengthener, a leavening agent, a ph control agent, and a texturizer. prepared by reacting gaseous carbon dioxide with aqueous ammonia. crystals of ammo- nium bicarbonate are precipitated from solution and subsequently washed and dried. Also known as hartshorn and rock ammonia, ammonium bicarbonate is soluble in water but decomposes when heated. It was used in place of ammonia when making ammonia-ripened gelatin emulsions.

• Verwenden

  Ammonium bicarbonate is a commonly used reagent for industrial and research procedures. It acts a good buffer in lyophilization and matrix assisted laser desorption. It is also utilized for the in-gel digestion of proteins by trypsin and in the MALDI mass spectrometric analysis of proteins. It is also used to make other ammonium compounds, in food processing, and for other uses. Ammonium bicarbonate can be used to study biological buffers. It is also used in a study that demonstrated that ammonium bicarbonate salts, which can be regenerated using low-temperature waste heat, can also produce sufficient voltage for hydrogen gas generation in a microbial reverse-electrodialysis electrolysis cells. It has also been used in a study that developed a fast and sensitive method for the simultaneous determination of Sudan dyes in food samples using partial filling micellar electrokinectic chromatography-mass spectrometry.

• Definition

  ChEBI: Ammonium bicarbonate is an organooxygen compound. It is a buffer applications such as lyophilization and matrix assisted laser desorption.

• Allgemeine Beschreibung

  A white crystalline solid having the odor of ammonia. Soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make other ammonium compounds, in food processing, and for other uses.

• Air & Water Reaktionen

  Soluble in water.

• Reaktivität anzeigen

  Heat > 36°C ( produces ammonia and carbon dioxide); strong acids and strong bases (CO2 and NH3) [Handling Chemicals Safely 1980 p. 141].

• Hazard

  Evolves irritating fumes on heating to 35C.

• Health Hazard

  Inhalation may cause respiratory irritation. Ingestion could be harmful. Contact with eyes or skin causes irritation.
  Breathing Ammonium Bicarbonate can irritate the nose, throat, and lungs causing coughing, wheezing, and/or shortness of breath. No risks to humans are expected from approved uses of ammonium bicarbonate as a pesticide active ingredient. The substance is approved as a food additive by the Food and Drug Administration (FDA) and as an inert pesticide ingredient by EPA. No toxic endpoints have been identified.

• Landwirtschaftliche Anwendung

  Ammonium hydrogen carbonate is another name for ammonium bicarbonate (NH4CO3), It is a low nitrogen containing fertilizer (17% N), used largely in China. It is produced by heating ammonium hydroxide with excess carbon dioxide, followed by evaporation of water.

• Sicherheitsprofil

  Poison by intravenous route. When heated to decomposition it emits toxic fumes of NO, and NH3

• mögliche Exposition

  It is used in leavening for some baked goods; in baking powders and fire extinguishers; to make dyes and pigments; in the manufacture of porous plastics; and as an expectorant.

• Versand/Shipping

  UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

• Inkompatibilitäten

  Contact with strong caustics, such as potassium hydroxide or sodium hydroxide will cause the release of ammonia gas. Decomposes as temperature rises ＞35 C.

• Waste disposal

  May be buried in a chemical waste landfill. If neutralized ammonium bicarbonate is amenable to treatment at a municipal sewage treatment plant.
