Disodium Phosphate Anhydrous powder Usage and Synthesis.

Disodium hydrogen phosphate is an inorganic chemical product, easy to weather, placed in the air at room temperature to lose about 5 water of crystallization and the formation of heptahydrate, heated to 100 ℃ when the loss of all the water of crystallization into anhydrous, 250 ℃ when the decomposition into sodium pyrophosphate.

It is easy to weather in the air, and very easy to lose five molecules of water of crystallization and form heptahydrate (Na2HPO4.7H2O). Soluble in water, insoluble in alcohol. Aqueous solution shows slightly alkaline reaction (0.1-1N solution). Disodium hydrogen phosphate is used as buffer, baking powder, feed additive, detergent and dyeing agent in fermentation industry.

It is also used to treat boiler water, as a quality improver and baking powder. In the food industry, the fermentation industry uses it as buffer, baking powder, feed additives, detergents, dyeing agents, and so on. Disodium hydrogen phosphate can also be used as a nutrient salt for sewage scavengers to help purify water quality.

Uses of Disodium Phosphate Anhydrous powder.

Disodium hydrogen phosphate can be used as water softener, fabric weight gainer, fire retardant, and used in glaze, solder, medicine, pigment, food industry and other phosphates.

It is also used as emulsifier, quality improver, nutritional enhancer, fermentation aid, chelating agent, stabilizer. Used as boiler water softener, flame retardant for fabric, wood and paper, glazing agent and soldering agent. Used in the production of detergents, cleaning agents for printing plates and mordants for dyeing.

It is used as stabilizer for hydrogen peroxide bleaching in printing and dyeing industry, and as 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 culture agent for monosodium glutamate, erythromycin, penicillin, streptomycin and sewage production chemical treatment products.

It is also used in electroplating and leather blending. In the food industry as a quality improver, PH regulator, nutrient fortifier.

Product Method of Bulk Disodium Phosphate Anhydrous powder.

Spray drying method will be dodecahydrate disodium hydrogen phosphate added to the dissolving tank heated to dissolve, add a small amount of industrial phosphoric acid, adjust pH8.8-9.0, solution temperature 80 - 85 ℃, pumped to the metering tank, atomized by the sprayer, atomizer selection of the two-flow type steam nozzle, vapor pressure 0.15 - 0.3Mpa, atomizer Steam flow guide angle and the level of 30 °, steam-liquid ratio (0.4 ~ 5): 1. Hot stove gas inlet temperature 650 - 750 ℃. Drying can be parallel flow, can also be countercurrent drying.

Such as countercurrent drying, the inlet temperature 620-650 ℃, the exit temperature 140-150 ℃. The finished product particle size of about 90μm accounted for 60%, moisture content <1%. Produce anhydrous disodium hydrogen phosphate finished product.
