Liquid technical ammonia

GOST 6221 - 90.

The chemical formula - NH3

Molecular weight (on the international nuclear weights of 1977) - 17,0304


Technical liquid ammonia is intended for use in the industry of mineral fertilizers and agriculture.

Depending on its purpose liquid ammonia is issued in three grades:

A - for nitric acid manufacture, for nitriding, as a coolant, for creation of protective atmospheres;

Ак - for transportation on the main ammonia lines;

B - for processing on fertilizers and for use in agriculture as nitric fertilizer.
