Sodium bicarbonate, commonly known as baking soda, is an important inorganic chemical raw material, widely used in chemical, pharmaceutical, food, metallurgy and other fields. In the field of chemical production raw materials, there are many upstream and downstream related products of sodium bicarbonate. The following are some of the main upstream and downstream related products:

upstream products:

1. Soda ash: Soda ash is one of the main raw materials of sodium bicarbonate, used to produce sodium bicarbonate. There is a mutual conversion relationship between soda ash and sodium bicarbonate in the production process.
2. Coal: Coal is the energy and heat source required in the production of sodium bicarbonate, and is used for heating and drying processes.

downstream products:

1. Food additives: Sodium bicarbonate as a food additive, can be used in baked goods as a leavening agent, so that the food volume expansion, taste more soft.
2. Pharmaceutical raw materials: Sodium bicarbonate can be used as raw materials in the pharmaceutical field for the production of antacids, antidotes and other drugs.
3. cleaning agent: sodium bicarbonate is alkaline and can be used as a cleaning agent to remove oil and stains.

In addition, the downstream related products of sodium bicarbonate also include chemicals in the fields of rubber, coatings, printing and dyeing, metallurgy, etc. For example, in the field of rubber, sodium bicarbonate can be used as a foaming agent for the production of rubber foam materials; in the field of coatings, sodium bicarbonate can adjust the pH value of the coating to improve the stability and weather resistance of the coating; in the field of printing and dyeing, Sodium bicarbonate can be used as a fixing agent to improve the color fastness of the dye.

In summary, there are many upstream and downstream related products of sodium bicarbonate, which are widely used in various fields. With the continuous development of science and technology, the application field of sodium bicarbonate will continue to expand.
