Key Properties
Potassium carbonate anhydrous (extra pure) is a widely used soluble alkali salt essential in glass, soap, and organic synthesis. It is a white crystalline powder that is hygroscopic in nature, meaning it can absorb moisture from the air. This compound is notable for its high purity level of 99%, making it suitable for applications requiring stringent quality standards. With a molecular weight of 138.21 g/mol, potassium carbonate is a key ingredient in various industrial processes, particularly in the production of glass and soaps, where it acts as a flux and pH regulator.
Also known as Potash, Kalium Carbonate.

- Substance
Potassium carbonate appears as a white crystalline powder and is highly hygroscopic, meaning it readily absorbs moisture from the environment. It is freely soluble in water, with a solubility of approximately 112 g/L at 20°C. The melting point of potassium carbonate is around 891°C, and it decomposes upon heating to form potassium oxide and carbon dioxide. The density of potassium carbonate is approximately 2.43 g/cm³. It has a pH value of around 11.5 in a 1% aqueous solution, indicating its basic nature.

Potassium carbonate is widely used in various industries due to its properties as a mild base and soluble alkali. In the glass manufacturing industry, it serves as a flux to lower the melting point of silica, facilitating the production of specialty glass. In soap manufacturing, it acts as a key ingredient in the saponification process, contributing to the formation of soap from fats and oils. Additionally, potassium carbonate is utilized in organic synthesis, particularly in reactions such as Suzuki coupling, where it acts as a base to facilitate the coupling of aryl halides with boronic acids. Its applications extend to agriculture as a fertilizer and in food processing as a food additive (E501). Overall, potassium carbonate is an essential compound in both industrial and laboratory settings.
