Product Description Product introduction
Chinese name: disodium hydrogen phosphate
English name: sodium hydrogen phosphate
Alias; disodium phosphate; anhydrous sodium phosphate; anhydrous sodium phosphate; anhydrous sodium phosphate; anhydrous sodium phosphate; anhydrous sodium phosphate Disodium;
CAS: 7558-79-4
EINECS number: 231-448-7
Melting point: 243-245 ° C
Density: 1.064 g / mL at 20 ° C
Characteristic and superiority
Disodium hydrogen phosphate in the air is easy to weather, at room temperature when placed in the air to lose about 5 crystal water and the formation of seven water, heated to 100 ° C when the loss of all the water from the water, 250 ° C decomposition into coke Sodium phosphate. Easy to weather in the air, easily lost five molecules of crystal water and the formation of seven water (Na2HPO4.7H2O). Soluble in water, insoluble in alcohol. The aqueous solution was slightly alkaline (0.1 ° N solution with a pH of about 9.0). In 100 ℃ loss of crystal water from anhydrous, 250 ℃ decomposition into sodium pyrophosphate. 1% aqueous solution has a pH of 8.8 to 9.2; insoluble in alcohol. Melting at 35.1 ° C and losing 5 crystal water.
Application
1, used as industrial water treatment agent, printing and dyeing detergent, quality improver, antibiotic culture agent, biochemical treatment agent
2, used as fabric, wood, paper flame retardant, silk weighting agent. Is the manufacture of reactive dyes additives. Used in soldering and brazing instead of borax.
3, for food quality improver
4, used as analytical reagents, buffers, softener and printing and dyeing industry fire agent, but also for fabric weight gain
5, used as analytical reagent and pH reference reagent
6, for wood, paper and fabric flame retardants, glaze and flux, dyeing with mordant, hydrogen peroxide bleach stabilizer, boiler softener, etc.
7, for the softener, fabric weighting agent, fire agent, and for glaze drugs, welding drugs, pharmaceuticals, pigments, food industry and the preparation of other phosphate for industrial water treatment agent, printing and dyeing detergents, quality improvers, Neutralizer, antibiotic culture agent, biochemical treatment agent food quality improver
8. For ICP-AES, AAS, AFS, ICP-MS, ion chromatography and so on. Standard solution for titration analysis.
