Ammonium bicarbonate Chemical Properties,Uses,Production


Ammonium bicarbonate (commonly known as ammonium hydrogen carbonate) is a mildly basic inorganic compound.
Ammonium bicarbonate is a commonly used reagent for industrial and research procedures. Ammonium bicarbonate is volatile in solution and releases ammonia and CO2. This property makes ammonium bicarbonate a good buffer for such applications as lyophilization and matrix assisted laser desorption. Ammonium bicarbonate is also utilized for the in-gel digestion of proteins by trypsin and in the MALDI mass spectrometric analysis of proteins.
Ammonium bicarbonate is used as a baking powder, in some food processing applications, in cough syrups and as antacid. It also has uses as a fertilizer, pH buffer, and reagent in chemical laboratories. In the industry, it is used in the manufacture of dyes, pharmaceuticals, catalysts, ceramics, fire-retardants, plastics and other products.

Nitrogen fertilizer

Ammonium bicarbonate is mainly used as fertilizers. After being applied to the soil, the ammonium ion (NH4 +) contained in ammonium bicarbonate can be absorbed by soil colloid or lattice-fixed or transformed into nitrate nitrogen. After being absorbed by plants, there are no accessory constituents remaining in the soil with a small impact on the soil pH. It is applicable to all kinds of soil and crops, soil without leaving any harmful substance residue for the soil and crops. It is quick-acting nitrogen fertilizer and can be subject to long-term usage.
In order to prevent the loss of fertilizer efficacy due to ammonia volatilization and the burning of the crop stems and leaves, we can apply deep placement and cover soil. It can be used as basic fertilizer for topdressing, but not suitable to be used as seed manure. When being used for topdressing, we should prevent the drop of ammonium bicarbonate onto the plant, to avoid ammonia hazards. The shortcoming of ammonium bicarbonate as a fertilizer lies in its chemical instability. After the addition of crystalline modifier, the crystal of ammonium bicarbonate is enlarged and the water content is reduced, reducing the phenomenon of easily subjecting to decomposition and agglomeration. Ammonium bicarbonate is one of nitrogen fertilizer industrial products, being the major varieties of small nitrogenous fertilizer plants in China, being one of the purification products of coke oven in the coking plant. Coking plant takes concentrated ammonia as raw materials for reaction with carbon dioxide to generate ammonium bicarbonate crystals with centrifugal filtering to obtain ammonium bicarbonate products.
Ammonium bicarbonate is easy to be subject to decomposition. It is appropriate to be packed with the combination of inner plastic film and external plastic bag or 3-layers of kraft paper sacks, both need to be sealed and stored in a warehouse of being cool, low-temperature, dry and ventilated to prevent moisture, rain and sun.

Chemical properties

It appears as white monoclinic or orthorhombic crystals. It is soluble in water, but insoluble in ethanol, carbon disulfide and concentrated ammonia.
It dissolves in water to give a mildly alkaline solution. It is insoluble in most organic solvents. While it is stable at room temperature (25 °C), it decomposes at temperatures above 36 °C to form ammonia, carbon dioxide, and water in an endothermic reaction (absorbs energy for the reaction from the surroundings).
NH4HCO3 → NH3 + CO2 + H2O
It reacts with acids to produce carbon dioxide, and reacts with bases to produce ammonia.


1. Ammonium bicarbonate is used as nitrogen fertilizer, being applicable to a variety of soils, can simultaneously provide the ammonium nitrogen and carbon dioxide demanded by crop growth. However, it contains low nitrogen content and is also easy to caking.
2. It can be used as analytical reagent as well as being used in synthesizing ammonium salt and fabric degreasing.
3. It can promote crop growth and photosynthesis; trigger seedlings and the growth of leaves. It can be used as topdressing as well as being directly applied as ground fertilizer as food leavening agent and bulking agent.
4. Ammonium bicarbonate can be used as a senior food fermentation agent. Its combination with sodium bicarbonate can be used as the raw materials of leavening agent such as bread, biscuits and pancakes. It can also be used as raw material of foam powder juice, as well as being used for the blanching of green vegetables and bamboo shoots. Moreover, it can be used as medicine and reagents.
5. Alkali; leavening agent; buffer; aerating agent.
Its combination with sodium bicarbonate can be used as the raw materials of leavening agent such as bread, biscuits and pancakes. Baking powder also takes this product as the main ingredient, together with the acidic substances. It can also be used as raw material of foam powder juice. The dosage of the blanching of green vegetables and bamboo shoots should be 0.1% to 0.3%.
6. It can be used as analytical reagent; used for ammonium salt synthesis. Pharmaceuticals; baking powder; dyeing; It can be used for fabric degreasing. It can also be used as foamed plastics.

Production method

Send the compressed carbon dioxide into the concentrated ammonia, and place it under the carbon dioxide pressure; simultaneously apply cooling; precipitate out the crystal; followed by centrifugal separation and dehydration to obtain the final product. Upon refining, dissolve it in water, and add ethanol to re-crystallize it.
Carbonization method: after the ammonia is absorbed by water; apply carbon dioxide for carbonization, followed by separation and drying to produce ammonium bicarbonate.
NH3 + CO2 + H2O → NH4HCO3
To the carbon dioxide gas originated from the lime kiln and be subject to cleaning and washing, send the ammonia to saturation, followed by centrifugal separation and hot air drying to obtain the finished products.
NH3 + CO2 + H2O → NH4HCO3

Chemical Properties

Ammoniumbicarbonate,NH4HC03, also referred to as ammonium hydrogencarbonate and ammonium acid carbonate, is a white solid, soluble in water,that forms by the reaction of anunoniumhydroxide and excess CO2.

Chemical Properties

Ammonium bicarbonate is a white crystalline solid with a faint ammonia odor.


A buffer applications such as lyophilization and matrix assisted laser desorption


In baking powder formulations; in cooling baths (one kg dissolved in 5 liters H2O at 17° lowers it to 7°); in fire extinguishers; manufacture of porous plastics, ceramics; manufacture of dyes, pigments; in compost heaps to accelerate decomposition; as fertilizer; for defatting textiles; in cold wave solutions; in chrome leather tanning; to remove gypsum from heat exchanges and other processing equipment.


Ammonium Bicarbonate is a dough strengthener, a leavening agent, a ph control agent, and a texturizer. prepared by reacting gaseous carbon dioxide with aqueous ammonia. crystals of ammo- nium bicarbonate are precipitated from solution and subsequently washed and dried.


White crystals made by carbonate salts acting upon ammonium hydroxide followed by crystallization. Also known as hartshorn and rock ammonia, ammonium bicarbonate is soluble in water but decomposes when heated. It was used in place of ammonia when making ammonia-ripened gelatin emulsions.

General Description

A white crystalline solid having the odor of ammonia. Soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make other ammonium compounds, in food processing, and for other uses.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Heat > 36°C ( produces ammonia and carbon dioxide); strong acids and strong bases (CO2 and NH3) [Handling Chemicals Safely 1980 p. 141].


Evolves irritating fumes on heating to 35C.

Health Hazard

Inhalation may cause respiratory irritation. Ingestion could be harmful. Contact with eyes or skin causes irritation.

Agricultural Uses

Ammonium bicarbonate, also called ammonium hydrogen carbonate (NH4HCO3), is a low nitrogen containing fertilizer (17%N), used largely in China. It is produced by heating ammonium hydroxide with excess carbon dioxide and evaporating the water formed.
Ammonium bicarbonate is a hygroscopic, white, crystalline compound soluble in water but insoluble in alcohol and acetone. It decomposes above 35℃ to ammonia, carbon dioxide and water vapor, releasing irritant fumes. Only 30% of the applied nitrogen of this fertilizer is recovered by plants owing to the unstable nature of ammonium bicarbonate.

Agricultural Uses

Ammonium hydrogen carbonate is another name for ammonim bicarbonate (NH4CO3), It is a low nitrogen containing fertilizer (17% N), used largely in China. It is produced by heating ammonium hydroxide with excess carbon dioxide, followed by evaporation of water.
