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

►Description

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.

►Origin

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.

►Production

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.

2KOH + CO2 → K2CO3 + H2O

ceramic production

►First Aid

Inhalation First Aid

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.
