Potassium hydroxide

Potassium hydroxide


Potassium hydroxide (chemical formula: KOH, formula weight: 56.11) white powder or flake solid. Melting point 360~406 ℃, boiling point 1320~1324 ℃, relative density 2.044g/cm, flash point 52 ° F, refractive index n20/D1.421, vapor pressure 1mmHg (719 ℃). It is strongly alkaline and corrosive. It can easily absorb moisture in the air and deliquescence, and absorb carbon dioxide to form potassium carbonate. Dissolve in about 0.6 parts hot water, 0.9 parts cold water, 3 parts ethanol and 2.5 parts glycerin. When dissolved in water, alcohol or treated with acid, a lot of heat is generated. The pH of 0.1mol/L solution is 13.5. Medium toxicity, median lethal dose (rat, oral) 1230mg/kg. Soluble in ethanol, slightly soluble in ether. It is extremely alkaline and corrosive, and its properties are similar to caustic soda.

Purpose:

Inorganic industry is used as raw materials for the production of potassium salts, such as potassium permanganate, potassium nitrite, potassium hydrogen phosphate, etc. The daily chemical industry is used as the raw material for manufacturing potassium soap, dirt washing soap, shampoo, cream, cold cream, shampoo, etc. The pharmaceutical industry is used to manufacture such raw materials as progesterone and vanillin. The dye industry is used to make melamine dyes. The battery industry is used to manufacture alkaline batteries. It is used as a desiccant and absorbent, for making potassium soap, oxalic acid and various potassium salts, and also for electroplating, carving, lithography, etc; It is mainly used as raw material for potassium salt production, such as potassium permanganate, potassium carbonate, etc.

Storage precautions

Store in a cool, dry and well ventilated warehouse. Keep away from kindling and heat source. The warehouse temperature shall not exceed 35 ℃ and the relative humidity shall not exceed 80%. The package must be sealed against moisture. It shall be stored separately from combustibles and acids, and mixed storage is strictly prohibited. The storage area shall be equipped with appropriate materials to contain the leakage.
