| | Cesium hydroxide Usage And Synthesis |
| Description | Cesium 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 Properties | colourless liquid (as a 50% solution in water) | | Chemical Properties | Cesium hydroxide is a colorless-to-yellow
crystalline compound. It is often used in a water solution.
| | Uses | Used to make porous cesium titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes.1 | | Uses | In storage-battery electrolytes; as catalyst in the polymerization of cyclic siloxanes. | | General Description | An aqueous solution. Strongly corrosive. Harmful to skin and eyes. Used in electric storage batteries. | | Air & Water Reactions | Dilution with water may generate enough heat to cause steaming or spattering. | | Reactivity Profile | 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. | | Fire Hazard | 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. | | Safety Profile | Poison by
intraperitoneal route. Moderately toxic by
ingestion. A powerful caustic. A corrosive
skin and eye irritant. See also CESIUM. | | Potential Exposure | 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. | | First aid | Move 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. | | Shipping | UN2682 Cesium hydroxide, Hazard class: 8;
Labels: 8-Corrosive material. UN2681 Cesium hydroxide,
solution, Hazard class: 8; Labels: 8-Corrosive material | | Incompatibilities | 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. |
