Product Description


CAS NO 584-08-7 Potassium carbonate K2CO3 historically used for soap, glass, and ceramic production




      Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in


ethanol) which forms a strongly alkaline solution. It can be made as the product of


potassium hydroxide's absorbent reaction with carbon dioxide. It is deliquescent,


often appearing a damp or wet solid. Potassium carbonate is used in the production


of soap and glass.



      Potassium carbonate is the primary component of potash and the more refined


pearl ash or salts of tartar. Historically, pearl ash was created by baking potash in a


kiln to remove impurities. The fine, white powder remaining was the pearl ash. The


first patent issued by the US Patent Office was awarded to Samuel Hopkins in 1790


for an improved method of making potash and pearl ash.


In late 18th century North America, before the development of baking powder, pearl


ash was used as a leavening agent in quick breads.



      Today, potassium carbonate is prepared commercially by the electrolysis of


potassium chloride. The resulting potassium hydroxide is then carbonated using


carbon dioxide to form potassium carbonate, which is often used to produce other


Potassium compounds.

►First Aid 




Inhalation First Aid


 Fresh air, rest.


Skin First Aid


Remove contaminated clothes. Rinse skin with plenty of water or shower.


Eye First Aid


First rinse with plenty of water for several minutes (remove contact lenses if easily


possible),then refer for medical attention.


Ingestion First Aid


Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink.


Refer for medical attention .


Fire Fighting


In case of fire in the surroundings, use appropriate extinguishing media.

Accidental Release Measures


Personal protection: particulate filter respirator adapted to the airborne


concentration of thesubstance. Sweep spilled substance into covered containers.


Wash away remainder with plenty of water.


Cleanup Methods


Accidental release measures. Do not let product enter drains

►Safe Storage 

Dry. Separated from strong acids.


Storage Conditions Keep tightly closed.


Potassium carbonate is stored in bunkers; the ventilation air must be dry because


of the hydroscopicity of the product.


Keep container tightly closed in a dry and well-ventilated place.
