The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. ... 50 ppm (35 mg/m 3) IDLH 300 ppm Flash point:
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
As early as in 1895, it was known that ammonia was 'strongly antiseptic... it requires 1.4 grams per litre to preserve beef tea (broth).' [79] In one study, anhydrous ammonia destroyed 99.999% of zoonotic bacteria in three types of animal feed, but not silage.

This ammonia is used as a feedstock for all other nitrogen fertilizers, such as anhydrous ammonium nitrate (NH 4 NO 3) and urea (CO(NH 2) 2). Deposits of sodium nitrate (NaNO 3) (Chilean saltpeter) are also found in the Atacama Desert in Chile and was one of the original (1830) nitrogen-rich fertilizers used. [35] It is still mined for ...
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4 OH), or a urea (CO(NH 2) 2) solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst. As the reaction drives toward completion, nitrogen (N 2), and carbon dioxide (CO 2), in the case of urea use, are produced. Selective catalytic reduction of NO
