The dodecahydrate is white crystal with relative density 1.52, weathered in the air easily, losing quinque-molecular crystallization water easily, forming anhydride after losing crystallization water at 100°C, decomposing to sodium pyrophosphate at 50°C; anhydride is white powder with hygroscopy. Both are easily soluble in water, aqueous solution is slightly alkaline, alcohols insoluble.
Uses:
Boiler water softening agent, fire retardant agent of textile, wood and paper, glaze and welding agent; used to produce detergent, printing cleaner and dye mordant; hydrogen peroxide bleaching stabilizer in printing and dyeing industry, rayon filling (increasing the intensity and elasticity); raw material for producing sodium pyrophosphate and other phosphate, cultured agent for gourmet, erythrocin, penicillin, streptomycin and sewage treatment equipment; also used in electroplating and tanning.
Packing and storage:
