  • Potassium carbonate Wikipedia

    Potassium carbonate is prepared commercially by the reaction potassium hydroxide with carbon dioxide: 2 KOH + CO 2 → K 2 CO 3 + H 2 O. From the solution crystallizes the sesquihydrate K 2 CO 3 · 3 ⁄ 2 H 2 O ("potash hydrate"). Heating this solid above 200 °C gives the anhydrous salt. Alternative method, potassium chloride is treated with carbon dioxide in the presence of an organic amine

    Potassium carbonate (K 2 CO 3) is a water-soluble inorganic compound that is primarily derived from potash. It is industrially prepared by reacting potassium hydroxide and carbon dioxide. The solution crystallizes to form potash hydrate, which can further be heated above 200°C to produce the anhydrous salt. Application K 2 CO 3 can be used for a variety of applications such as: • production
