  • Chemische Eigenschaften colourless liquid (as a 50% solution in water)
  • Chemische Eigenschaften Cesium hydroxide is a colorless-to-yellow crystalline compound. It is often used in a water solution.
  • Physikalische Eigenschaften White to yellowish fused crystalline mass; highly deliquescent; very alkaline; density 3.68 g/cm3; melts 272°C; highly soluble in water; soluble in ethanol; aqueous solution is very alkaline.
  • Verwenden Cesium hydroxide is used in the preparation of porous cesium titanosilicates, which are potential ion-exchange materials utilized for radioactive wastes cleaning purpose. It is also involved in the preparation of other cesium salts. Further, it is used as an electrolyte in alkaline batteries and as a catalyst in organic synthesis. In addition to this, it is used in color photography.
  • Verwenden Used to make porous cesium titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes.1
  • Verwenden In storage-battery electrolytes; as catalyst in the polymerization of cyclic siloxanes.
  • Verwenden Rubidium hydroxide (RbOH) is very hygroscopic (absorbs large amounts of water for its weight). It is also an excellent absorber of carbon dioxide. Rubidium hydroxide can be used to etch glass and as an electrolyte in low-temperature electric storage batteries for use in vehicles in the subarctic.
  • synthetische Cesium hydroxide is prepared by electrolysis of cesium salts to obtain cesium metal, which then reacts with water to yield hydroxide. It also is prepared by the action of barium hydroxide with an aqueous solution of cesium sulfate.
  • Allgemeine Beschreibung An aqueous solution. Strongly corrosive. Harmful to skin and eyes. Used in electric storage batteries.
  • Air & Water Reaktionen Dilution with water may generate enough heat to cause steaming or spattering.
  • Reaktivität anzeigen CESIUM HYDROXIDE,SOLUTION 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 A poison. Skin, eye, and upper respiratory tract irritant.
  • 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.
  • Sicherheitsprofil Poison by intraperitoneal route. Moderately toxic by ingestion. A powerful caustic. A corrosive skin and eye irritant. See also CESIUM.
  • mögliche Exposition Cesium hydroxide may be used as a raw material for other cesium salts; such as the chloride which in turn may be used to produce cesium metal. Cesium metal is used in electronic devices.
  • Versand/Shipping UN2682 Cesium hydroxide, Hazard class: 8; Labels: 8-Corrosive material. UN2681 Cesium hydroxide, solution, Hazard class: 8; Labels: 8-Corrosive material
  • Inkompatibilitäten Cesium hydroxide is the strongest base known. Keep away from all acids. It must be stored in silver or platinum and out of contact with air because of its reactivity with glass. CsOH causes the generation of considerable heat in contact with water or moisture. Contact with many organic compounds, many metals (i.e., aluminum, lead, tin, zinc), glass, oxygen, or carbon dioxide causes a violent reaction.
