Product Description

CAS NO 584-08-7  White powder potash is used primarily as an agricultural







        Potash 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.








      Potassium carbonate (chemical formula: K2CO3), also known as potash; its


appearance is colorless crystal or white granules and is easily soluble in water with


its solution being strongly alkaline. Cool its saturated solution with generating


glassy monoclinic crystalline hydrate 2K2CO3 • 3H2O separated. It has a density of


2.043. It will lose its crystal water at 100 ℃. It is insoluble in ethanol, acetone and


ether. It has a strong hygroscopic effect and can absorb carbon dioxide and water


upon exposure to air to be converted into potassium bicarbonate. It can be


generated through the reaction between potassium hydroxide with carbon dioxide


to give.

      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.

       Potash is used primarily as an agricultural fertilizer (plant nutrient) because it is


a source of soluble potassium, one of the three primary plant nutrients.



 Preventative Measures


Hand protection: handle with gloves. Eye protection: safety glasses.


Skin and Body protection: choose body protection according to the amount and


concentration of the dangerous substance at the work place.Handle in accordance


with good industrial hygiene and safety practice. Wash hands before breaks and at


the end of workday.


Accidental release measures. Use personal protective equipment. Avoid dust


formation. Avoid breathing dust.


If breathed in, move person into fresh air. If not breathing give artificial respiration.


Consult a physician.


In case of skin contact, wash off with soap and plenty of water.


Consult a physician.


In case of eye contact, rinse thoroughly with plenty of water for at least 15 minutes


and consult a physician.


If swallowed, never give anything by mouth to an unconscious person. Rinse mouth


with water.
