Disodium hydrogenorthophosphate Identification Name Disodium hydrogenorthophosphate Synonyms Sodium hydrogen phosphate; Disodium monohydrogen phosphate Molecular Formula Na2HPO4 Molecular Weight 141.96 CAS Registry Number 7558-79-4 EINECS 231-448-7 Properties Water solubility >=10 g/100 mL at 20 ºC Product Description Disodium hydrogenorthophosphate Sodium hydrogen phosphate Molecular formula: Na2HPO4. CAS: 7558-79-4 Appearance: White crystal Properties: Colorless transparent sheet inclined department rhombus crystals, relative density 1.52, in the air, and easily easy to lose five molecules formed seven water gesso item (Na2HPO4.7H2O). Soluble in water, not soluble in alcohol. Solution a micro alkaline reaction (0.1-1N solution pH about 9.0). In 100 degree lost without water gesso into things, 250 when degree decomposed into coke sodium. Use: Used for boiler soft agent, fabric, wood and paper paper of flame retardants, glaze medicine and changzhou. Used in the production of detergent, print the detergents and dyeing with salt. In printing and dyeing industries as hydrogen peroxide bleaching stabilizer, rayon packing (enhancement of silk strength and elastic). Is manufacturing focal phosphorus sodium and other raw materials, but also of phosphate monosodium glutamate, erythromycin, penicillin, streptomycin, and sewage production processs of cultivating agent products etc. Also used in electroplating, Rou leather.
