[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods, main properties of sodium bicarbonate

Sodium bicarbonate properties

Sodium bicarbonate, chemical formula for NaHCO, also known as baking soda or sodium bicarbonate, is a white crystalline powder or granular solid, with a slight alkaline. It has high solubility in water and releases carbon dioxide gas when dissolved, so it has foaming properties. This chemical decomposes when heated to form sodium carbonate, water and carbon dioxide. The chemical properties of sodium bicarbonate is relatively stable, but in the face of strong acid or strong alkali will occur chemical reaction, the formation of carbon dioxide gas and the corresponding salts. Because of its non-toxic, tasteless and buffering capacity, sodium bicarbonate is widely used in industry and daily life.

Sodium bicarbonate use

Sodium bicarbonate is widely used and covers many industries. In the food industry, it is used as a leavening agent, mainly for baking food, so that the dough fermentation and produce pores, enhance the taste and volume of food. In medicine, sodium bicarbonate is used in the preparation of antacids and foaming tablets to help neutralize stomach acid and relieve stomach discomfort. It can also be used for emergency treatment of acidosis patients. Sodium bicarbonate is also a commonly used cleaning agent, suitable for cleaning fruits and vegetables and household cleaning, because of its good decontamination ability and low corrosion. Industrially, sodium bicarbonate is used to produce other chemicals, such as soda ash and carbon dioxide gas, and is also used in water treatment and waste gas treatment to help neutralize acids.

Sodium bicarbonate upstream and downstream raw materials

The production of sodium bicarbonate mainly depends on natural raw materials and synthetic chemical reactions. Its main upstream feedstocks include sodium carbonate (Na CO₂), carbon dioxide (CO₂) and water. Industrial production usually uses the Solvay or Holsoli method, which uses basic raw materials such as sodium chloride (NaCl) and limestone (CaCO) to generate sodium bicarbonate through a series of chemical reactions. The specific process includes: first, the sodium chloride solution reacts with ammonia gas to generate ammonium chloride and ammonia water, then carbon dioxide is introduced to react with ammonia water to generate ammonium bicarbonate, and finally reacts with sodium chloride to generate sodium bicarbonate and ammonium chloride. Downstream industries include food processing industry, pharmaceutical manufacturing industry, chemical manufacturing industry and environmental protection. Sodium bicarbonate is further processed and applied as raw material or intermediate in these fields.

Sodium bicarbonate storage method

Although the chemical properties of sodium bicarbonate are relatively stable, it is still necessary to pay attention to moisture and pollution during storage. It should be stored in a dry and ventilated environment to avoid being affected by moisture, because sodium bicarbonate is easy to absorb water and agglomerate in a humid environment, which will affect its use effect. Avoid storage with acidic substances to prevent chemical reactions that can generate carbon dioxide gas and cause pressure rise or container rupture. The storage container should be a plastic bag or plastic barrel with good sealing performance, and the product name, batch number, production date and precautions should be marked on the outside of the container to facilitate management and use. During transportation, avoid exposure to high temperature environment, and take measures to prevent leakage and damage to ensure the safe transportation of sodium bicarbonate.

Sodium Bicarbonate Market Prospects

With the increasing demand for environmental protection and efficient production in various industries, the market demand for sodium bicarbonate also shows an increasing trend. In the food industry, consumer demand for healthy foods has driven the use of sodium bicarbonate as a natural leavening agent. In the field of medicine, with the improvement of people's health awareness, sodium bicarbonate has a broad application prospect in antacid drugs and drugs to relieve stomach discomfort. The strengthening of environmental protection policies has also increased the demand for sodium bicarbonate in wastewater treatment and waste gas treatment. With the continuous improvement of production technology and the reduction of production costs, the market supply of sodium bicarbonate will be more sufficient, and the price will tend to be stable, which is conducive to the wide application of various industries.

Conclusion

As an important chemical, sodium bicarbonate has a wide range of applications and stable market demand. Its good chemical properties make it widely used in food, medicine, industry and environmental protection. Through scientific and reasonable storage and transportation methods, the quality and use effect of sodium bicarbonate can be guaranteed. With the progress of technology and the increase of market demand, the application prospect of sodium bicarbonate will be broader. In the future, the production and application of sodium bicarbonate will pay more attention to environmental protection and sustainable development, and help the green development of various industries.
