Sodium Phosphate Disodium Phosphate AnHydrous CAS 7558-79-4 is an important chemical raw material, which is widely used in biological fermentation, food, medicine, feed, chemical industry and agriculture. The main manufacturing methods of disodium hydrogen phosphate are neutralization method, extraction method, ion exchange method, complex decomposition method, direct method, crystallization method and electrolysis method.
Disodium hydrogen phosphate can be used as a water softener, fabric weight enhancer, fire retardant, and in glazes, solder, medicine, pigments, food industry and other phosphates. Emulsifier quality improver, nutrient enhancer, fermentation assistant, chelating agent, stabilizer. Used as boiler water softener, flame retardant for fabrics, wood and paper, glaze and solder. It is used in the production of detergents, cleaning agents for printing plates and mordant for dyeing. In the printing and dyeing industry, it is used as a stabilizer for hydrogen peroxide bleaching and a filler for rayon (to enhance the strength and elasticity of the silk). It is a raw material for the manufacture of sodium pyrophosphate and other phosphates, and also a culture agent for monosodium glutamate, erythromycin, penicillin, streptomycin and sewage production and chemical treatment products. Also used for electroplating, blending leather. Used in the food industry as quality improvers, PH regulators, nutrient fortifiers.
