Technical grade ammonia (liquid)
Technical grade ammonia (aqueous)
Ammonia (aqueous reagent grade)
Technical grade ammonia (liquid)
GOST (State standard) 6221?90
NH3
Use:
Technical grade ammonia (liquid) is used in industry and agriculture:
- Grade A technical ammonia (liquid) is used for production of nitric acid and for nitration; as refrigerant and for production of shielding atmospheres.
- Grade B technical ammonia (liquid) is used for production of nitrogen fertilizers and as an independent fertilizer.
Characteristics:
Toxic colorless clear liquid, non-flammable, transforms into gas under normal temperature and normal atmosphere pressure. Ammonia gas compound with oxygen creates explosive mixture. Class of hazard with regard to impact on human body – 4.
Package:
The product is poured into special tank-cars, road-tankers, and steel cylinders.
Transportation:
The product is shipped by rail in special railway tank-cars, covered railway-cars, and multipurpose containers, as well as by road transport in special tank-trucks and steel cylinders in accordance with the shipping rules for the corresponding kind of transport.
Guaranteed shelf life:
1 year

Technical grade ammonia (aqueous)
GOST (State standard) 9?92
NH4ОН
Use:
- Grade A technical ammonia (aqueous) is widely used in production (particularly in pulp-and-paper and hydrolysis production);
- Grade B technical ammonia (aqueous) is used in agriculture as nitrogen fertilizer.
Characteristics:
Non-flammable and in-explosive, but degasification of ammonia vapors can create explosive concentrations. Class of hazard with regard to impact on human body – 4.
Transportation:
The product is shipped in railway tank-cars and tank-trucks in accordance with the shipping rules for the corresponding kind of transport.
Guaranteed shelf life:
3 months
