化学的特性

White, deliquescent pieces, lumps, sticks, pellets, or flakes having a crystalline fracture. Keep well stoppered, absorbs water and carbon dioxide from the air. Soluble in water, alcohol, glycerol; slightly soluble in ether.

化学的特性

Potassium hydroxide is a white deliquescent solid.

化学的特性

Potassium hydroxide occurs as a white or nearly white fused mass. It is available in small pellets, flakes, sticks and other shapes or forms. It is hard and brittle and shows a crystalline fracture. Potassium hydroxide is hygroscopic and deliquescent; on exposure to air, it rapidly absorbs carbon dioxide and water with the formation of potassium carbonate.

使用

Potassium hydroxide is used in making liquidsoap and potassium salts, in electroplatingand lithography, in printing inks, as a mordantfor wood, and finds wide applicationsin organic syntheses and chemical analyses.

使用

Potassium Hydroxide is a water-soluble food additive and bleaching agent. upon exposure to air it readily absorbs carbon dioxide and moisture and deliquesces. it is used to destroy the bitter chemical constituents in olives that will be used as black olives.

使用

potassium hydroxide is used as an emulsifier in lotions and as an alkali in liquid soaps, protective creams, and shaving preparations. Depending on the concentration used, it can be highly irritating to the skin and/or cause a burning sensation.

使用

Pharmaceutic aid (alkalizing agent).

調製方法

Potassium hydroxide is made by the electrolysis of potassium chloride. Commercial grades may contain chlorides as well as other impurities.

一般的な説明

A white solid. Corrosive to metals and tissue. Used in soap manufacture, bleach, as an electrolyte in alkaline batteries, and as a food additive.

空気と水の反応

Hydrolysis generates enough heat to ignite adjacent combustible material [Haz. Chem. Data 1966]. Dissolves in water (with liberation of heat, may steam and spatter. Solution is basic (alkaline). Deliquescent

反応プロフィール

POTASSIUM HYDROXIDE absorbs moisture readily forming caustic solution that attacks aluminum and zinc. A piece of potassium hydroxide causes liquid chlorine dioxide to explode [Mellor 2:289. 1946-47]. 1,2-dichloroethylene and potassium hydroxide forms chloroacetylene, which is explosive and spontaneously flammable in air. Potassium hydroxide is highly toxic [Rutledge 1968. p. 134]. A reaction between n-nitrosomethylurea and potassium hydroxide in n-butyl ether resulted in an explosion due to the formation of diazomethane [Schwab 1972]. Potassium persulfate and a little potassium hydroxide and water ignited a polythene (polyethylene) liner of a container by release of heat and oxygen [MCA Case History 1155. 1955]. Using potassium hydroxide to dry impure tetrahydrofuran, which contains peroxides, may be hazardous. Explosions have occurred in the past. Sodium hydroxide behaves in a similar way as potassium hydroxide [NSC Newsletter Chem. Soc. 1967]. A strong base. Forms caustic solution in water. [Merck 11th ed. 1989].

危険性

Toxic by ingestion and inhalation, strong caustic, handle with gloves or tongs, corrosive to tissue. Eye, skin and upper respiratory tract irritant.

健康ハザード

Causes severe burns of eyes, skin, and mucous membranes.
Potassium hydroxide is a strongly alkaline, hydrophilic substance and therefore solid potassium hydroxide is highly corrosive. It reacts with fat and can cause irreversible damage to any site of contact with the body (for example skin or eyes). Solutions of potassium hydroxide in water at concentrations above 0.5% (w/w) are irritating at points of contact and, at higher concentrations, the solutions can be corrosive. Potassium hydroxide does not cause skin allergies. Because of the corrosive properties of potassium hydroxide, its ingestion can be fatal. Under normal conditions of handling and use, potassium hydroxide in solution will dissociate into its constituent ions and, if ingested, will not be systemically available in the body as such.

健康ハザード

Potassium hydroxide is extremely corrosiveto tissues. Its corrosive action is greater thanthat of sodium hydroxide. It gelatinizes tissuesto form soluble compounds that maycause deep and painful lesions (ACGIH1986). Contact with the eyes can damagevision. Ingestion can cause severe pain in thethroat, vomiting, and collapse.
LD50 value, oral (rats): 365 mg/kg
Exposure to its dusts can cause irritationof the nose and throat.

火災危険

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.

燃焼性と爆発性

Sodium hydroxide and potassium hydroxide are not flammable as solids or aqueous solutions.

応用例(製薬)

Potassium hydroxide is widely used in pharmaceutical formulations to adjust the pH of solutions. It can also be used to react with weak acids to form salts.
Therapeutically, potassium hydroxide is used in various dermatological applications.

安全性プロファイル

Poison by ingestion. An eye irritant and severe human skin irritant. Very corrosive to the eyes, skin, and mucous membranes. Mutation data reported. Ingestion may cause violent pain in throat and epigastrium, hematemesis, collapse. Stricture of esophagus may result if substance is not immedately fatal. Above 84' it reacts with reducing sugars to form poisonous carbon monoxide gas. Violent, exothermic reaction with water. Potentially explosive reaction with bromoform + crown ethers, chlorine dioxide, nitrobenzene, nitromethane, nitrogen trichloride, peroxidized tetrahydrofuran, 2,4,6- trinitrotoluene. Reaction with ammonium hexachloroplatinate(2-) + heat forms a heat- sensitive explosive product. Violent reaction or ignition under the appropriate condtions with acids, alcohols, p-bis(l,3- dbromoethyl)benzene, cyclopentadene, germanium, hyponitrous acid, maleic anhydride, nitroalkanes, 2-nitrophenol, potassium peroxodisulfate, sugars, 2,2,3,3- tetrafluoropropanol, thorium dicarbide. When heated to decomposition it emits toxic fumes of K2O. See also SODIUM HYDROXIDE.

安全性

Potassium hydroxide is widely used in the pharmaceutical and food industries and is generally regarded as a nontoxic material at low concentrations. At high concentrations it is a corrosive irritant to the skin, eyes, and mucous membranes.
(rat, oral): 0.273 g/kg

職業ばく露

KOH is generally used as an alkali and in the manufacture of other potassium compounds.

貯蔵

splash goggles and impermeable gloves should be worn at all times when handling these substances to prevent eye and skin contact. Operations with metal hydroxide solutions that have the potential to create aerosols should be conducted in a fume hood to prevent exposure by inhalation. NaOH and KOH generate considerable heat when dissolved in water; when mixing with water, always add caustics slowly to the water and stir continuously. Never add water in limited quantities to solid hydroxides. Containers of hydroxides should be stored in a cool, dry location, separated from acids and incompatible substances.

貯蔵

Potassium hydroxide should be stored in an airtight, nonmetallic container in a cool, dry place.

輸送方法

UN1814 (solution) & UN1813 (solid); Potassium hydroxide, solid or solution, Hazard class: 8; Labels: 8-Corrosive material.

純化方法

Its carbonate content can be reduced by rinsing KOH sticks rapidly with water prior to dissolving them in boiled out distilled water. Alternatively, a slight excess of saturated BaCl2 or Ba(OH)2 can be added to the solution which, after shaking well, is set aside so that the BaCO3 is allowed to separate out. Davies and Nancollas [Nature 165 237 1950] rendered KOH solutions carbonate free by ion exchange using a column of Amberlite IR-100 in the OH-form.

不和合性

A strong base. Violent reaction with acids, alcohols, water, metals (when wet), halogenated hydrocarbons; maleic anhydride. Heat is generated if KOH comes in contact with water and carbon dioxide from the air. Corrosive to zinc, aluminum, tin and lead in the presence of moisture releasing combustible/explosive hydrogen gas. Can absorb water from air and give off sufficient heat to ignite surrounding combustible materials.

不和合性

Potassium hydroxide is a strong base and is incompatible with any compound that readily undergoes hydrolysis or oxidation. It should not be stored in glass or aluminum containers, and will react with acids, esters, and ethers, especially in aqueous solution.

廃棄物の処理

Dilute with large volume of water, neutralize and flush to sewer

規制状況(Regulatory Status)

GRAS listed. Accepted for use in Europe in certain food applications. Included in the FDA Inactive Ingredients Database (injections, infusions, and oral capsules and solutions). Included in nonparenteral and parenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
