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.
