Ammonia, Ammonia, NH3, colorless gas. Has a strong irritating odor. The density is 0.7710. Relative density 0.5971 (air = 1.00)
Easily liquefied into a colorless liquid. It can be liquefied by pressing at normal temperature (critical temperature 132.4 ° C, critical pressure 11.2 MPa, which is 112.2 MPa)
Pressure). Boiling point is -33.5 ° C. It is also easily solidified into a snow-like solid. Melting point -77.75 ° C. Soluble in water, ethanol and ether. Decomposes into
Nitrogen and hydrogen have a reducing effect. In the presence of a catalyst, it can be oxidized to nitric oxide. For making liquid nitrogen, ammonia, nitric acid, ammonium salts and amines
Wait. It can be produced by the direct synthesis of nitrogen and hydrogen, which can burn the mucous membranes of the skin, eyes and respiratory organs. Excessive inhalation by humans can cause lung swelling.

The main purpose:
Ammonia is used in the manufacture of ammonia, nitrogen fertilizers (urea, ammonium carbonate, etc.), compound fertilizers, nitric acid, ammonium salts, soda ash, etc., and is widely used in chemical, light industry,
Fertilizer, pharmaceutical, synthetic fiber and other fields. Nitrogen-containing inorganic salts and organic intermediates, sulfa drugs, polyurethanes, polyamide fibers and nitrile rubber
All need to use ammonia directly as raw material. In addition, liquid ammonia is often used as a refrigerant, and ammonia can also be used as a biofuel to provide energy.
