Product Description

Base Information:
Ammonium bicarbonate is a colorless or light-colored compound, granular, plate-like or columnar crystals, specific gravity 1.*7, bulk density of 0.*5, compared with ammonium sulfate (0.*6) light, slightly heavier than granular urea (0.*6) soluble in water, 0 ℃ when the solubility of *1.3%; *0 ℃ when *1%; *0 ℃ when *5%.

White orthorhombic or monoclinic crystals. Non-toxic. Ammonia smell. Density 1.*8g / cm3. Soluble in water, aqueous solution is alkaline, insoluble in ethanol. The nature of instability, more than *6 ℃ decomposed into carbon dioxide, ammonia and water, *0 ℃ can be broken down completely. Hygroscopic, accelerated decomposition after deliquescence.

Chemical Properly:
1. stable at room temperature under atmospheric pressure, to avoid contact with acid oxides, thermal instability, solid at *8 deg.] C, the decomposition of an aqueous solution at *0 deg.] C.
The solubility in water of *4% (*0 ℃), *7.4% (*0 ℃), *1.3% (*0 ℃). Their solution was alkaline, *5 ℃ when the pH value of 7.8 0.1mol·L*1 solution. Chemically unstable ammonium bicarbonate, thermal decomposition. Heated to about *0 ℃, the decomposition of NH3 *1.5%, CO2 *5.7%, H2O *2.8% composed of white smoke. Hot water can be decomposed. In the presence of moisture under normal pressure, more than *6 ℃ began to slowly decompose to produce ammonia, carbon dioxide and water.
Soluble in water (at 0 ℃: *1.9g / **0 ml; *0 ℃ when: *7g / **0 ml), aqueous solution is alkaline, pH 0.*8% aqueous solution is 7.8. Soluble glycerol, **0 ℃ when broken down into carbon dioxide and ammonia. Hygroscopic, absorbing and releasing moisture after pungent odor of ammonia, there is no smell of ammonia in the dry state. In the air easily weathered.

Application:
1. Nitrogen is used for a variety of soil, can provide ammonium and carbon dioxide required for the growth of crops at the same time, but low nitrogen content, easy caking
2. reagents for the analysis, but also for the synthesis of ammonium fabric and skim foam used as chemical fertilizers and plastics
Raw material with sodium bicarbonate for use as bread, biscuits, pancakes, etc. leavening agent. Yi Yi This product is the main ingredient of baking powder, together with an acidic substance. Also used as a foaming powder juice raw materials. When blanching using 0.1% to 0.3% green vegetables, bamboo shoots. It was used as agricultural fertilizer
3. for chemical leavening agent, can be used for all kinds of provisions to be added leavening agent food, according to production needs appropriate to use.
