Soap glass and china products were the main application for Carbonate of potash K2CO3​

►Description

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.

►Specification

china production.

►Notice

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.

►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.
