Anhydrous liquefied ammonia
Anhydrous liquefied ammonia is used mainly for the production of urea, ammonium nitrate, concentrated nitric acid in various branches of industry and agriculture, for the production of aqueous solutions that are used in medicine, for the national economy and other chemical industries. Export is possible.
Anhydrous liquefied ammonia, under normal temperature and atmospheric pressure is in the condition of gas. Ammonia gas refers to combustible gases, liquid ammonia - to the slow-burning substances. It refers to toxic substances to the 4th class of danger.
Anhydrous liquefied ammonia depending on the area of application is available in three grades:
A - for the production of nitric acid, nitrating, as a coolant, for protective atmospheres;
B - for processing on fertilizers and for agricultural use of nitrogen fertilizer.
Safety precautions: At normal temperature and atmospheric pressure is in the gaseous state. Gaseous ammonia refers to combustible gases, liquid ammonia to flame-retardant substances. By the degree of influence on the human body refers to toxic substances to the 4th class of danger.
