    Product Usage

    In baking powder formulations, in cooling baths, in fire extinguishers, manufacture porous plastics, ceramics, manufacture dyes, pigments, in compost heaps to accelerate decompn, as fertilizer, for defatting textiles, in cold wave solns, in chrome leather tanning, to remove gypsum from heat exchanges and other processing equipment.

    Production Methods

    (1) the compressed carbon dioxide into the concentrated ammonia, and placed in the carbon dioxide pressure, while cooling, precipitation of the crystal, the centrifugal separation, dehydration. When it was purified, it was dissolved in water, and ethanol was added to recrystallize it. Carbonization method Ammonia is absorbed by water, carbonized with carbon dioxide, and then separated and dried to produce ammonium bicarbonate.
    (2) from the lime kiln and cleaned by the washing of CO2 gas, into the ammonia to saturation, after centrifugal separation, hot air drying derived products.
    (3) the industrial ammonium bicarbonate added to the amount of water, and slowly into the ammonia. Heated to 40 ~ 50 ° C, stirring until no longer dissolved so far. Add a small amount of activated carbon, at 40 ~ 50 ℃ for a certain time. The solution was filtered, the solution cooled and carbon dioxide was bubbled through. And then by suction filtration crystallization, is pure ammonium bicarbonate. Carbon dioxide can also be passed through the saturated ammonia crystallization process in the system. Carbonization method Ammonia is absorbed by water, carbonized with carbon dioxide, and then separated and dried to produce ammonium bicarbonate
    .(4) The compressed carbon dioxide into the concentrated ammonia, and carbon dioxide placed under pressure, while cooling, precipitation of the crystal, the centrifugal separation, dehydration. When it was purified, it was dissolved in water, and ethanol was added to recrystallize it.
    (5) A slight excess of barium hydroxide solution was added depending on the content of SO42- ions in the solution Solution. Insulation standing 1h, hot filter, the filtrate access to a larger jar, stopper on the inlet and outlet. Outlet access to distilled water bottle. Until the solution is cooled, the first ammonia to Xian bottle of distilled water is no longer absorb The crystals were filtered off and dried at room temperature (about 2 ~ 3h) For 2 hours to give the final ammonium bicarbonate.
