The field of medicine

In medicine, sodium hexametaphosphate can prepare various drugs with antibacterial, anti-inflammatory, anti-tumor and other effects. For example, sodium hexametaphosphate can form complexes with specific metal ions to treat diseases like cancer. 

Chemical industry

In chemical engineering, sodium metaphosphate can prepare various phosphates for fertilizers, plastics, coatings and other materials. For example, sodium hexametaphosphate can be reacted with sodium hydroxide to produce sodium phosphate salt, which is used to produce phosphate fertilizer and compound fertilizer. In addition, sodium hexametaphosphate can also be used as an additive in the production of plastics, coatings and other materials to improve the performance and stability of materials.

Water treatment field

Sodium hexametaphosphate is also widely used in the field of water treatment. It can be used as a scale inhibitor and corrosion inhibitor to prevent the formation of scale and corrosion of metal. For example, sodium hexametaphosphate can inhibit scale formation in industrial cooling water and improve cooling efficiency. In addition, sodium hexametaphosphate can be used to prepare water treatment agents, cleaning agents, etc., for purifying water quality and cleaning equipment.

Production Method of Sodium Hexametaphosphate：

Chemical synthesis

Chemical synthesis is one of the leading production methods of sodium hexametaphosphate. This method synthesized sodium hexametaphosphate by chemical reaction using orthophosphate as raw material. The specific steps are as follows:

The phosphoric acid is heated to a specific temperature, and an appropriate amount of catalyst, such as sulfuric acid, sodium sulfate, etc., is added.

Under a certain pressure, maintain a particular reaction time for orthophosphate polymerization reaction, oligophosphate.

The hypophosphate was further heated and polymerized to obtain sodium hexametaphosphate.

The sodium hexametaphosphate product was obtained by centrifugal separation and drying.

The advantages of chemical synthesis are a mature production process, large yield and stable product quality. However, this method needs to use a lot of acid substances such as sulfuric acid, which is particularly polluting to the environment. In addition, the reaction conditions of this method are relatively harsh, requiring high temperature and high-pressure conditions, so the production cost is high.

Pyrolysis method

Pyrolysis is when orthophosphate or oligophosphate is decomposed into sodium hexametaphosphate by heating it. The primary raw material of this method is orthophosphate or oligophosphate, which is decomposed by high-temperature heating and then processed by crystallization and separation; sodium hexametaphosphate product is obtained.

The advantages of pyrolysis are a simple production process and low cost. However, this method requires high-temperature equipment, and the high-temperature resistance performance of the equipment is required. In addition, the quality of pyrolysis products is slightly inferior to that of chemical synthesis, and there may be problems with darker colors and lower purity.

In actual production, different production methods can be selected according to different needs and raw materials. For large-scale, high-quality production, chemical synthesis is more suitable; For small-scale, low-cost production, the pyrolysis method is more suitable. At the same time, paying attention to environmental protection and safety in the production process is necessary.
