Liquid ammonia

(anhydrous ammonia, gaseous ammonia, hydrogen nitride, Freon 717, R717)

Liquid ammonia (anhydrous ammonia, gaseous ammonia, hydrogen nitride, Freon 717, R717) - is flammable toxic gas with a strong specific smell. A mixture of ammonia and air is explosive. Maximum pressure in the explosion of the ammonia-air mixture 7 times the initial. Its self-ignition temperature is 630°С. The most flammable concentration is 24.5% (≥180 g/m3). Anhydrous ammonia is used to obtain the lowest possible temperature, in production of fertilizers, and as the raw material other organic synthesis. Minimum ignition energy is 680 mJ. Contact with mercury, chlorine, iodine, bromine, calcium, silver oxide and to some other chemicals can also lead to the formation of explosive compounds. Ammonia anhydrous reacts with copper, zinc and their alloys, especially in the presence of water; It dissolves the usual rubber.

Liquid ammonia (anhydrous ammonia, gaseous ammonia, hydrogen nitride, Freon 717, R717) causes severe irritation of mucous membranes, lachrymation and asphyxia, on contact with skin causes severe burns. In handling with liquid ammonia (anhydrous ammonia, gaseous ammonia, Freon 717, R717) should follow safety rules and use personal protection equipment.

Liquid ammonia (anhydrous ammonia, gaseous ammonia, hydrogen nitride, Freon 717, R717) is pack in steel cylinders working under pressure. Filling (charging, pumping) factor not more than 0,5 kg on 1 dm3 of cylinder capacity. The product is stored in warehouse of the respective category, under a canopy or in open air avoiding direct sunlight. All types of carriage in compliance with hazardous goods rules transport liquid ammonia (anhydrous ammonia, gaseous ammonia, hydrogen nitride, Freon 717, R717).
