Disodium phosphate (DSP)

Chemical formula: Na2HPO4.nH2O(n=0,12)

Alias: sodium hydrogen phosphate or sodium phosphate dibasic

Molecular weight: 358.0

Executive standard: HG/T2965-2009 (industrial grade) GB25568-2010 (food grade)

Traits:

Dodecahydrate is a white crystal with a relative density of 1.52. It is easy to weather. It melts at 35°C and loses 5 crystal water. It becomes anhydrous at 100°C and becomes sodium pyrophosphate at 250°C; anhydrous is white powder. Easily deliquescent; both are easily soluble in water, and the aqueous solution is weakly alkaline and insoluble in alcohol.

Use:

Dodecahydrate is used as a boiler water softener, flame retardant for fabrics, wood and paper, as a detergent, as a glaze and solder, as a stabilizer for hydrogen peroxide bleaching in printing and dyeing, monosodium glutamate, erythromycin, penicillin, chain Culture agent for mycin and sewage biochemical treatment products, used in electroplating, etc.; used in the food industry to make baking powder, quality improvers, emulsifiers, nutritional fortifiers, fermentation aids, binders; anhydrous It is used as flame retardant, silk weighting agent, reactive dye additive, and used instead of borax in welding and brazing.

Package:
Plastic inside and outside woven, net weight of each bag is 25KG, 50KG, stored in a dry and ventilated place
