Potassium carbonate is an inorganic substance, which is a colorless or white hexagonal or rhombohedral crystal or granular powder. It is soluble in water and insoluble in ethanol, acetone, and carbon disulfide; Highly hygroscopic, it can absorb carbon dioxide and moisture when exposed to air, transforming into potassium bicarbonate with a bitter and salty taste. The production methods of potassium carbonate include wood ash method, L ü bulan method, electrolysis method, ion exchange method, etc. The commonly used methods are electrolysis and ion exchange.

The function and use of potassium carbonate

1. It is the raw material for producing electronic tubes, television picture tubes, and computer monitor glass shells.

2. Glass enamel industry is used for preparing enamel powder to enhance its leveling properties; Adding it to glass serves as a melting aid and improves the transparency and refractive index of the glass.

3. Used for producing welding electrodes, it can prevent arc breakage during welding.

4. The dye industry is used to manufacture Yin Dan Tu Lin, Disperse Red 3B, Reduced Ash M, etc.

5. The printing and dyeing industry is used for the dyeing of vat dyes and the whitening of ice dyeing.

6. Absorbents for removing hydrogen sulfide and carbon dioxide.

7. Mixing with soda ash can be used as a dry powder fire extinguishing agent.

8. Used for the processing of exposed photosensitive materials.

9. Can be used as an auxiliary raw material for acetone and alcohol production, and as an anti-aging agent in rubber production.

10. Used for removing hydrogen sulfide and carbon dioxide from industrial gases.

11. The woolen cotton industry is used for boiling cotton fabrics and degreasing wool.

12. Preparation of various potassium salts. Raw materials for food additives such as potassium sorbate and potassium dihydrogen phosphate.

13. Used in the photography industry for the processing of exposed photosensitive materials.

14. Used as a flux for silicates and insoluble sulfates.

15. Water absorbing agent for organic liquids.

16. Used for analyzing reagents. Such as high-purity analysis, emission spectroscopy analysis, etc.

17. Used as a desiccant in chemical experiments.

Due to its moderate water absorption capacity, it can form potassium carbonate (K2CO3 · 2H2O) with two crystalline waters, but it reacts slowly with water. Suitable for drying neutral organic compounds such as alcohols and esters, as well as general alkaline organic compounds such as amines and alkaloids. But it cannot be used as a desiccant for acids, phenols, or other acidic substances.

18. The carbonate ions in potassium carbonate are nutrients for crop photosynthesis, which can promote and enhance plant photosynthesis.

19. It can increase soil temperature, neutralize soil acidity, and enable crops to grow in a suitable soil pH environment.

20. It has good soil disinfection and sterilization effects, as well as underground pest control effects.

21. Supplement potassium nutrition and replenish various trace elements removed from the soil due to the harvest of crop seeds.

22. Food grade potassium carbonate is an additive used in the production of instant noodles and carbonated beverages, which plays a role in leavening and preservation.

23. Food grade potassium carbonate is also used to improve color and enhance flavor. When used in conjunction with sodium carbonate, it can simultaneously improve the elasticity and extensibility of food. As an alkaline agent and dough improver, it can inhibit the sourness of noodles and is suitable for noodle products. In addition, it also plays a coloring role, improves product quality, and is mainly used for the processing of pastry.
