Product Description

 

Product Description

 

Disodium hydrogen phosphate (DSP)can be used to produce citric acid, water softener, fabric weight enhancer, flame retardant, glaze flux, flux, medicine, pigment, food industry and other phosphates as industrial water treatment agent, printing and dyeing detergent, quality improver, quality improver, neutralizer, antibiotic maintenance agent, biochemical treatment agent
Food quality improvers.
Disodium hydrogen phosphate is easily weathered in the air. When it is placed in the air at normal temperature, it loses about 5 water of crystallization and forms heptahydrate. When it is heated to 100 ºC, it loses all water of crystallization and becomes anhydrous. When it is heated to 250 ºC, it decomposes into sodium pyrophosphate. It is easy to be weathered in the air and can easily lose five molecules of water of crystallization to form heptahydrate.
Soluble in water, insoluble in alcohol. The aqueous solution exhibits a slightly alkaline reaction (the pH of 0.1-1N solution is approximately 9.0). It loses water of crystallization at 100 ºC and becomes anhydrous, and decomposes into sodium pyrophosphate at 250 ºC. The pH value of 1% aqueous solution is between 8.8 and 9.2; Insoluble in alcohol. Melt and lose 5 water of crystallization at 35.1 ºC.

• In Food Industry:It is used as a food additive. It can be used as a pH regulator to control the acidity and alkalinity of food, maintain the stability of food flavor and texture, and is often used in dairy products, beverages, and canned fruits. It can also be used as a chelating agent to chelate metal ions and prevent the discoloration and deterioration of food. In addition, it can be used as a buffering agent to maintain the stability of the food system.
• In Ph Industry:It is used in the preparation of some drugs. For example, it is used as a buffer in the formulation of certain oral liquids and injections to maintain the stability of the drug solution. It can also be used as a phosphorus supplement in some nutritional preparations to prevent and treat hypophosphatemia. In addition, it is used in some laxatives to help clean the intestinal tract before medical examinations such as colonoscopy10.
• In Industrial Field:It is used in the leather industry to pretreat leather, helping to remove impurities and improve the quality of leather. In the textile industry, it is used as a dyeing assistant to improve the dyeing effect. It is also used in water treatment to adjust the pH value of water and remove some metal ions. In the production of detergents, it can be used as a builder to enhance the cleaning effect. In addition, it is used in the production of paper, ceramics, and other industries.
• In Agricultural Field:It can be used as a fertilizer to provide phosphorus and sodium elements for plants, promoting the growth and development of plants. It is especially suitable for some soils lacking phosphorus and sodium. In addition, it can also be used in the preservation of fruits and vegetables to prolong the storage period.
