Potassium hydroxide
Description
Potassium hydroxide KOH 48% Liquid or 90% 95%Flakes (chemical formula :KOH, formula :56.11) white powder or flake solid. The melting point was 360~406ºC, the boiling point was 1320~1324ºC, the relative density was 2.044g/cm, the flash point was 52°F, the refractive index was N20 /D1.421, the vapor pressure was 1mmHg(719ºC). Highly alkaline and corrosive. Very easy to absorb moisture in the air and delirium, absorb carbon dioxide and become potash. Soluble in about 0.6 parts hot water, 0.9 parts cold water, 3 parts ethanol and 2.5 parts glycerin. A great deal of heat is produced when dissolved in water, alcohols, or treated with acids. The pH of 0.1 molar solution is 13.5. Medium toxicity, half of the lethal dose (rats, through the mouth)1230mg/kg. Soluble in ethanol, slightly soluble in ether. It is highly alkaline and corrosive, and its properties are similar to caustic soda.
Product Information:
Nature: White or slightly yellow bean shaped particles, rods, or blocks. Melting point approximately 360 ºC, d 2 044. 380 ºC is anhydrous. It is highly hygroscopic and deliquescent in the air, absorbing carbon dioxide to form potassium carbonate. Dissolve in 0.9 parts of water, 0.6 parts of boiling water, 3 parts of ethanol, and 2.5 parts of glycerol, while releasing a large amount of heat. Insoluble in ether. The pH value of the Imol/L aqueous solution is 13.5. Non combustible and highly corrosive. When exposed to water and steam, a large amount of heat is released, forming a corrosive solution. Neutralize with acid and release heat.
