Urea 46%

Production Detail:

In common with most commercial nitrogen fertilizers, urea is manufactured from anhydrous ammonia (NH3).

The high analysis of urea—46% N—is the main reason for the low cost of this form of nitrogen fertilizer. Freight costs and storage and handling are all lower than with lower analysis fertilizers such as ammonium nitrate (34-0-0) or ammonium sulfate (21-0-0).
Urea 46% Nitrogen a white crystalline solid containing 46% nitrogen, is widely used in the agricultural industry as an animal feed additive and fertilizer.
Fertilizer urea can be purchased as prills or as a granulated material.

In the past, it was usually produced by dropping liquid urea from a “prilling tower” while drying the product. The prilled formed a smaller and softer substance than other materials commonly used in fertilizer blends. Today, though, considerable urea is manufactured as granules. Granules are larger, harder, and more resistant to moisture. As a result, granulated urea has become a more suitable material for fertilizer blends.

CAS No.: 57-13-6

Synonym: synthetic urea , Amide of carbonic acid, carbamide, carbamide acid, carbonyl diamide, carbonyl diamide, carbonyl diamine, isaurea.

Uses / Applications: While over 90% of urea produced is used as a fertilizer, it has other uses, which include the manufacture of the melamine, used in melamine-methanal resins. Urea itself also forms important resins. An increasingly important use of urea is in reducing air pollution from diesel engines in cars, buses and lorries.
