dibasic Sodium phosphate

molecular formula: Na2HPO4.12(H2O)Appearance:Colorless transparent 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 °C lost without water gesso into things, 250 when °C 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.
