K₂CO₃‌‌

Potassium Carbonate - Food Grade & Industrial Grade

Pharmaceutical industry: used to manufacture long-acting sulfonamides, progesterone, cortisone, tadalafil, estradiol benzoate and other drugs.
Food industry: can be used as acidity regulator, nutritional supplement, processing aid, spices, etc., usually added in appropriate amounts when making noodles and wontons, which can give the products unique flavor, color and toughness.
Dyes and printing and dyeing: used to manufacture dyes such as indanthite, disperse red 3B, and vat gray M, as well as for printing and dyeing of vat dyes and whitening of ice dyes.

Potassium Carbonate Information

The following are multi-dimensional tags about Potassium Carbonate (K₂CO₃‌‌), covering properties, applications, classifications, etc., which can be selected according to specific scenarios:

Basic Attribute Tags

Chemical formula: K₂CO₃. Molecular weight: 138.025. CAS number: 584-08-7. Appearance: Colorless hygroscopic crystals or hygroscopic white powder

Chemical Properties

Thermal stability: It will decompose at high temperatures to produce toxic fumes of potassium oxide, but its thermal stability is relatively high and it will not decompose even when heated to 1000°C. Reaction with acids: It can react with acids such as nitric acid, sulfuric acid, and hydrochloric acid to produce the corresponding potassium salt and release carbon dioxide.

Physical Properties

Density: 2.29g/cm³. Melting point: 891℃. Boiling point: None (high temperature decomposition). Solubility: Very soluble in water, difficult to dissolve in alcohol and acetone. Hygroscopicity: Very easy to deliquesce in humid air, absorbs moisture and carbon dioxide in the air, and generates potassium bicarbonate.

Classification

Material category: inorganic compounds, potassium salts, carbonates. Industrial grade: generally divided into industrial grade and food grade, etc. Industrial potassium carbonate is further divided into type I (general industrial use) and type II (mainly used to manufacture cathode ray tube glass shells).

Safety and Storage

It should be stored in a cool, dry, well-ventilated warehouse, away from fire and heat sources, and prevent direct sunlight. The package must be sealed and must not be exposed to moisture. It should be stored separately from acids, oxidants, etc. and must not be mixed.

Related Industries

Upstream raw materials: mainly potassium chloride, magnesium carbonate, water, carbon dioxide, potassium sulfate, limestone, coal powder, etc., and can also be extracted from wood ash. Downstream products: can be further processed into other potassium salts, potash and other compounds, and can also be used to produce glass products, ceramic products, medicines, dyes, etc.
