Disodium Hydrogen Phosphate powder Usage and Synthesis.

Food industry: Disodium hydrogen phosphate is widely used as a food additive because of its stability and safety. In bakery products such as bread and biscuits, it helps to regulate the acid-base balance of the food, improves the stability of the food and makes the product taste fluffier. 

Pharmaceutical industry: In the pharmaceutical industry, disodium hydrogen phosphate dodecahydrate is used in the preparation of certain drugs to provide a stable pH environment for drug production. It can also be used as a raw material or auxiliary ingredient in the production of tablets, capsules and so on. 

Chemical analysis: In the field of chemical analysis, disodium hydrogen phosphate is commonly used in titrimetric analysis, spectrophotometric analysis and so on. It can react with certain metal ions to produce soluble complexes, which facilitates the determination of metal ions. 

Water treatment: Because of its good water solubility and stability, disodium hydrogen phosphate is often used as a coagulant in the water treatment industry, which helps to remove suspended solids and heavy metal ions in sewage, and regulate the acidity and alkalinity of sewage. 

Agriculture: As a plant growth regulator, disodium hydrogen phosphate promotes plant growth and development by regulating soil pH. It can also be used as a fertiliser additive to increase the phosphorus content of the soil. 

Industrial cleaning: in industrial cleaning industry, disodium hydrogen phosphate dodecahydrate is often used as water softener, metal chelating agent and suspending agent due to its good chelating, suspending and dispersing properties. Effectively removes dirt from metal surfaces. 

Uses and functions of Disodium Hydrogen Phosphate.

It is a work quality improver, which has the effect of increasing the complex metal ions, pH value and ionic strength of foodstuffs, thus improving the adhesion and water-holding property of foodstuffs. China's regulations can be used for condensed milk, the maximum use of 0.5g/kg; can also be used for complex baking powder, according to the production needs of the appropriate amount of use.

Used as boiler water softener, flame retardant for fabric, wood and paper, glaze and solder. Used in the production of detergents, cleaning agents for printing plates and mordants for dyeing. Used as stabiliser for peroxide bleaching in printing and dyeing industry, filler for rayon (to enhance the strength and elasticity of silk). It is the raw material for the manufacture of sodium pyrophosphate and other phosphates, and is also the culturing agent for monosodium glutamate, erythromycin, penicillin, streptomycin and sewage biochemical treatment products. It is also used in electroplating and leather tanning.

Preparation of Disodium Hydrogen Phosphate.

Product Method of Bulk Disodium Hydrogen Phosphate.

(1) Recrystallisation method. Industrial dodecahydrate disodium hydrogen phosphate dissolved in hot water, after the removal of arsenic and heavy metals by sulfide, decolourisation with activated carbon, and then adjusted to PH8.2-8.4 with food phosphoric acid, after filtration, cooling crystallisation, centrifugal separation, drying that is, the product.

(2) Thermal phosphoric acid method. It is obtained by neutralising hot phosphoric acid with soda ash or sodium hydroxide. Sodium hydroxide or soda ash added to concentrated phosphoric acid, control PH for 8.9-9.0. neutralisation solution after filtration, concentration to a relative density of 1.24-1.26 (26-30 ° Bé) and cooled to 35 ° C below crystallisation. Centrifugal separation, drying that is the product, mother liquor sent to the neutralisation process for reuse.
