The physical properties of potassium carbonate include:
Common name: Potassium carbonate.
English name: potassium carbonate
CAS Number: 584-08-7
Molecular weight: 13821
Chemical Formula: The chemical formula of potassium carbonate is K2CO3.
Physical Properties: Potassium carbonate is a colorless crystalline solid that is deliquescent in air.
Chemical properties: Potassium carbonate can react with acids to form carbon dioxide, and can form precipitates with metal ions.
Appearance: Colorless crystalline solid.
Solubility: It is easily soluble in water and is an alkaline solution.
Density: about 243 g ml.
Melting Point: The melting point is about 891 degrees Celsius.
Deliquescence: It is deliquescent in the air and absorbs carbon dioxide and moisture.
Potassium carbonate has a variety of uses, including but not limited to the following:
1.Glass manufacturing: used as a raw material in glass production.
2.Desiccant: It can be used as a desiccant to absorb moisture in the air.
3.Raw materials and production: It is used in soap manufacturing, fertilizer production and the dye industry.
4.Manufacture of other compounds: as a raw material for other compounds, such as the preparation of alkaline compounds or metal carbonates.
5.Laboratory use: used for laboratory reagents, such as adjusting pH value.
The upstream products of potassium carbonate mainly include potassium chloride, limestone and carbon dioxide. Downstream products include glassware, soaps, fertilizers, dyes and pharmaceuticals.
Potassium carbonate is usually synthesized by a double displacement reaction of potassium chloride and sodium bicarbonate (limestone). The specific steps are as follows:
1.Dissolve potassium chloride with sodium bicarbonate in water.
2.Sodium carbonate and sodium chloride are formed through the reaction.
3.Crystallize with sodium carbonate solution and sodium chloride mixture.
4.Separation crystallization yields a mixture of sodium carbonate and sodium chloride.
5.Finally, the resulting mixture of sodium carbonate and sodium chloride is pyrolytically decomposed to produce potassium carbonate and sodium chloride.
This is the basic route for the synthesis of potassium carbonate.
The transportation and storage of potassium carbonate requires the following attention:
Transport.
1.Packaging: It should be sealed and protected from moisture and sun to avoid moisture, heat or direct sunlight.
2.Marking: There should be a clear mark on the packaging, indicating the name of the chemical, the hazard nature, the manufacturer's information, etc.
3.Protective measures: It is necessary to prevent collision and friction during transportation, and avoid mixed loading and loading.
Storage.
1.Environmental requirements: Store in a dry, well-ventilated warehouse, away from fire and heat sources.
2.Temperature: Keep away from high temperature or fire sources to avoid decomposition when heated.
3.Anti-corrosion: Keep away from acids to prevent chemical reactions.
In general, transport and storage should be kept dry, protected from heat and moisture, and precautions should be taken to ensure safety.
When using potassium carbonate, the following should be noted:
1.Personal protection: Wear protective glasses and chemical gloves when using to avoid ** or eye contact with potassium carbonate solution.
2.Ventilation: Good ventilation should be ensured during operation to avoid inhalation of vapors.
3.Avoid mixing: Avoid mixing with acids to avoid harmful chemical reactions.
4.Storage location: Keep away from flammable materials, acids and food when storing to avoid accidents.
5.Disposal: Waste potassium carbonate needs to be disposed of in accordance with local regulations to avoid environmental pollution.
The above are some of the things you need to pay attention to when using potassium carbonate to ensure safe use and strengthen relevant protection.
