The combustion heat was 5660.952 kJ / mol. Insoluble in water, soluble in ethanol, ether, acetone, acetic acid, benzene and petroleum ether.Flash point (closed) 71.2 °C. Explosion limit in air 0. 8 ~ 6 ~ s% (volume).

Purpose:
Used as a flame retardant for fabric, wood, paper, silk weight booster. It is an auxiliary agent for making reactive dyes. Used instead of borax in welding and brazing.

Preparation

The spray drying process is as follows: disodium hydrogen phosphate dodecahydrate is added into a solution solution tank to heat and dissolve,Add a small amount of industrial phosphoric acid, adjust the pH value 8.8 ~ 9.0, the solution temperature 80 ~ 85 °C, pump to the metering tank, atomized by the sprayer, the atomizer uses a two-stream steam nozzle, the steam pressure 0. 15 ~ 0. 3 MPa, the nebulizer steam guide angle is 30., vapor-liquid ratio (0.4 ~ 5): 1.Hot furnace gas inlet temperature 650 ~ 750 °C.It can be desiccated in parallel or countercurrent.Such as counter-current drying, the import temperature 620 ~ 650 °C, the export temperature 140 ~ 150 °C.The particle size of the finished product is about 90 um, accounting for 60%, and the moisture content is < 1%.The product of anhydrous disodium phosphate was prepared.
