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.
Appearance:This product is a white solid, in the form of small pellets, thin sheets, rods, or other shapes; Firm and brittle, with crystalline fracture surfaces; Easy to absorb moisture and carbon dioxide from the air.This product is highly soluble in water and easily soluble in ethanol.
Executive standards:GB/T 1919-2014
