Soap glass and china products were the main application for Carbonate of potash K2CO3
Potassium carbonate (molecular formula: K2CO3), also known as potash or
pearl ash, appears as a white powder or as colorless solid crystal with salty taste
and deliquescence. It can be dissolved in water to form a strongly alkaline solution.
However, it is insoluble in organic solvents such as ethanol. It has wide
applications. For example, it can be used as a drying agent, buffering agent and a
source of potassium in laboratory. It can also be used for the manufacturing of fire
extinguishers, soap, glass, and soften water. In addition, it is also used during the
production of cocoa powder to balance pH. Moreover, it can be supplied to
effervescent tablets which can conveniently provide potassium when there are low
levels of potassium in the blood for patients caused by various kinds of factors. In
industry, potassium carbonate is manufactured though first performing electrolysis
of potassium chloride to generate potassium hydroxide, followed by reaction with
carbon dioxide to derive the product. It is toxic upon eye contact, inhalation and
ingestion. For rats, it has an oral LD50 being 1870 mg/kg. It has chronic effects on
humans, causing damage to the mucous membranes, skin, and eyes.
Potassium carbonate is produced by the following methods of manufacture:
(1)By electrolysis of potassium chloride followed by exposing the resultant
potassium to carbon dioxide;
(2)By treating a solution of potassium hydroxide with excess carbon dioxide to
produce potassium carbonate;
(3) By treating a solution of potassium hydroxide with carbon dioxide to produce
potassium bicarbonate, which is then heated to yield potassium carbonate.

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. Consult a physician.
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.
