Potassium carbonate History

1、Potassium carbonate was first identified in 1742 by Antonio Campanella and is the primary component of potash and the more refined pearlash or salts of tartar.
2、The first patent issued by the U.S. Patent Office was awarded to Samuel Hopkins in 1790 for an improved method of making potash and pearlash.
3、In late 18th century North America, before the development of baking powder, pearl ash was used as a leavening agent in "quick breads".

Potassium carbonate Specification

Potassium carbonate , its CAS NO. is 584-08-7, the synonyms are Carbonic acid, dipotassium salt ; Dipotassium carbonate . Potassium carbonate (K₂CO₃) is a white salt, soluble in water (insoluble in ethano), which forms a strongly alkaline solution. It is deliquescent, often appearing a damp or wet solid. Potassium carbonate is used in the production of soap and glass.

Properties about Potassium carbonate are: (1)mp: 891 °C(lit.); (2)density: 2.43 g/mL at 25 °C; (3)storage temp.: Store at RT.; (4)solubility H2O: 1 M at 20 °C, clear, colorless; (5)form: powder; (6)Water Solubility: 1120 g/L (20 oC); (7)Sensitive: Hygroscopic; (8)Merck: 14,7619; (9)BRN: 4267587;

Preparation of Potassium carbonate: Today potassium carbonate is prepared commercially by the electrolysis of potassium chloride. The resulting potassium hydroxide is then carbonated using carbon dioxide to form potassium carbonate, which is often used to produce other potassium compounds.

2KOH + CO₂ → K₂CO₃ + H₂O

Uses of Potassium carbonate: Potassium carbonate is being used as the electrolyte in many cold fusion experiments. It is sometimes used as a buffering agent in the production of mead or wine. It is also used as a fire suppressant in extinguishing deep fat fryers and various other B class related fires. It is used in reactions to maintain anhydrous conditions without reacting with the reactants and product formed. It may also be used to pre-dry some ketones, alcohols, and amines prior to distillation. It is mixed with distilled water to make a safer electrolyte for oxyhydrogen production than potassium hydroxide, the more commonly used electrolyte. In cuisine, it is used as an ingredient in the production of grass jelly, a food consumed in Chinese and Southeast Asian cuisines.

When you are using this chemical, please be cautious about it as the following:
1. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
2. Wear suitable protective clothing;
3. Wear suitable gloves and eye/face protection;

You can still convert the following datas into molecular structure:
