Research Direction and Future Development of Granular Alkali

This article reviews the application and research progress of granulated bases in the fields of industry, medicine, and food. Firstly, the basic properties and preparation methods of granulated alkali are introduced, and then the application status and prospects of granulated alkali in the fields of industry, medicine, and food are discussed. Finally, the research direction and future development of granulated alkali are prospected.
Sodium bicarbonate (NaHCO3), also known as baking soda or baking soda powder, is an important chemical raw material. Granular alkali has a variety of physical and chemical properties, and is widely used in industry, medicine, food, and other fields. With the continuous progress of science and technology, the research and application of granular alkali have also been continuously expanded and deepened. The purpose of this article is to review the research progress in the application of granulated bases in the fields of industry, medicine, and food, providing reference for further research and application of granulated bases.

Granular alkali production and procurement
Granular alkali is a white crystal or powder that tastes like alkali, is easily soluble in water, and is insoluble in alcohol. Its chemical formula is NaHCO3, its relative molecular weight is 84.01, and its density is 2.159g/cm3. The pH value of granulated alkali is 8.3-8.6, which can neutralize weak acids and has the effect of neutralizing gastric acid.
There are various methods for preparing granulated alkali, among which the method using natural sodium ammonium as raw material is the most commonly used. The chemical reaction equation for this method is:
Na2CO3·NH4HCO3 → NaHCO3 + NH3↑ + H2O
The procurement of granular alkali production has learned that in this reaction, natural ammonium sodium and sodium carbonate are mixed in a certain proportion, and undergo a high-temperature reaction and cooling crystallization process to finally obtain granular alkali. The by-products are ammonia and water.
