Cesium hydroxide Usage And Synthesis
DescriptionCesium Hydroxide, as a water-soluble source of cesium, is typically found in any of several hydrate forms. Its applications are relatively limited due to its volatility and high basicity – corroding glass – as well as the high cost of cesium extraction. These applications include use as an electrolyte in alkaline batteries, particularly below the freezing point of water, in color photography, and as a catalyst for synthesis of organics such as phenylacetylene and polymers. Furthermore, it also finds use as a precursor in the manufacture of cesium salts.
Chemical Propertiescolourless liquid (as a 50% solution in water)
Chemical PropertiesCesium hydroxide is a colorless-to-yellow crystalline compound. It is often used in a water solution.
UsesUsed to make porous cesium titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes.1
UsesIn storage-battery electrolytes; as catalyst in the polymerization of cyclic siloxanes.
General DescriptionAn aqueous solution. Strongly corrosive. Harmful to skin and eyes. Used in electric storage batteries.
Air & Water ReactionsDilution with water may generate enough heat to cause steaming or spattering.
Reactivity ProfileCESIUM 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].
HazardA poison. Skin, eye, and upper respiratory tract irritant.
Health HazardTOXIC; 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.
Fire HazardNon-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.
Safety ProfilePoison by intraperitoneal route. Moderately toxic by ingestion. A powerful caustic. A corrosive skin and eye irritant. See also CESIUM.
Potential ExposureCesium 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.
First aidMove victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

IncompatibilitiesCesium 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.
