General description

Potassium carbonate (K2CO3) 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

K2CO3 can be used for a variety of applications such as:
  • production of soaps and glasses
  • drying agent for organic based compounds like ketones, alcohols, and amines
  • buffering agent to produce wine
  • ingredient in welding and other coatings
