  EPA: Pesticides - Ammonium Bicarbonate (073401) Fact sheet
Ammonium bicarbonate, a natural chemical, has a faint ammonia smell because it slowly decomposes to ammonia, carbon dioxide, and water.
Ammonium bicarbonate is a clear white crystalline solid with a faint ammonia smell.
Use of ammonium bicarbonate as a pesticide active ingredient will lead to negligible increases in human exposure to ammonium bicarbonate and ammonia based on current uses.

  Ammonium bicarbonate - Facts, Information, and Encyclopedia Reference article
Ammonium bicarbonate is formed as shown above and also by passing carbon dioxide through a solution of the normal compound, when it is deposited as a white powder, which has no smell and is only slightly soluble in water.
Ammonium bicarbonate decomposes at 36 to 60 °C into ammonia, carbon dioxide and water vapor in an endothermic process (as it is with many ammonium salts) and so causes a drop in the temperature of the water.
Ammonium bicarbonate is still widely used in the plastic and rubber industry, in the manifacture of ceramics, in chrome leather tanning and for the synthesis of catalysts.

 Summary of Data on Ammonium Bicarbonate
Ammonium bicarbonate is commonly used as a leavening agent inbaking powder formulations, a fertilizer, and a flavorant in tobacco, products, and has numerous commer- cial applications.
Ammonium bicarbonate is used by the tobacco industry as a flavorant during the nicotine extraction process, making: the resulting tobacco, less harsh than non- treated tobacco..

Ammonium bicarbonate reacts with acids to yield gaseous carbon dioxide and with alkalis to yield gaseous ammonia.
Ammonium bicarbonate is used as a leavening agent in baking dry flat cakes, e.g., biscuits and cookies.
Ammonium bicarbonate should not be stored or transported with nitrates, e.g., sodium nitrate, as a violent reaction may occur.

 Performance Products Group - Church & Dwight Co., Inc.
Ammonium bicarbonate reacts rapidly to the presence of moisture and /or heat to release NH3 + CO2 gases which contribute to leavening.
Use of ammonium bicarbonate without a leavening acid is limited to products whose final moisture is less than 5% so the ammonia gas can be baked out.
Ammonium bicarbonate can be used in combination with other chemical leavening systems to modify the appearance and eating quality of a product.

With basis on the fungus growth curve, the mycelia masses were obtained after 10, 20, 30, and 40 days of incubation, which correspond, respectively, to the beginning, middle and end of the log phase, and beginning of the decline phase.
With Coca liquid and ammonium bicarbonate there was no significant difference between the extracts obtained from cultures with different incubation times.
With the mycelia extracts, and the extractor liquids Coca and ammonium bicarbonate, it was shown that all the bands were similar, and only one band more with 20.96 kDa (Coca 10) with 10 days of incubation, also found with ammonium bicarbonate (BA 10).

Preferably, the sodium bicarbonate and/or ammonium bicarbonate is present in a range of 0.5% to 4% of the dry weight of the tobacco.
Within the extruder the sodium bicarbonate and/or ammonium bicarbonate is decomposed, and thus carbon dioxide gas is formed, the CO.sub.2 gas being released from the extrudate downstream of the die.
As to the web-form extrudate issued from the extruder die water in the in the extrudate flashed off to steam, whereby a cellular interior structure was imparted to the extrudate, this effect being enhanced by the release of CO.sub.2 gas by virtue of the inclusion of the sodium bicarbonate in blend fed to the extruder.

The only diffe rence between these active ingredients is that the anion attached to the quaternary ammonium cation is carbonate/bicarbonate in the case of Carboquat 150 T, whereas chloride is the anion in DDAC.
Based on the toxicological properties of the very chemically similar compound DDAC, the two active ingredients in Carboquat 150 T, didecyl dimethyl ammonium carbonate and didecyl dimethyl ammonium bicarbonate, would be expected to have moderate toxicity via oral and inhalation exposures and to cause severe skin and eye irritation.

In our region of China, ammonium bicarbonate is the least expensive source of ammonia and is readily available.
One tonne of the chopped RS was treated with 100 kg ammonium bicarbonate and 400 kg water for 30 days at ambient temperature of 15-20ºC. The treated straw was exposed to the air for a minimum of 24 h before feeding to animals to allow free ammonia to escape.
Treatment of RS with ammonium bicarbonate resulted in a significant improvement in body weight change of sheep and in feed conversion rate (both total diet DM and supplement DM per unit liveweight gain).

The process uses an ammonium bicarbonate draw solution to extract water from a saline feed water across a semi-permeable polymeric membrane.
Very large osmotic pressures generated by the highly soluble ammonium bicarbonate draw solution yield high water fluxes and can result in very high feed water recoveries.
Upon moderate heating, ammonium bicarbonate decomposes into ammonia and carbon dioxide gases that can be separated and recycled as draw solutes, leaving the fresh product water.
