ammonium carbamate are as an ammoniating agent and as an intermediate in the production of urea, a component of chemical fertilizers. In addition, ammonium carbamate is also used in pesticides and fumigants to control rodents and insects. Ammonium carbamate production . There are no available applicable toxicity data for ammonium carbamate; however, because the use of ammonium carbamate is restricted for use only as an inert More Information; Description: Beilstein Number: 3914091 Uses: Ammonium carbamate is used in the production of fertilizers by acting as an ammoniating agent. For most applications, ammonium carbamate substitutes ammonia.

Hazard classification and labelling. Ammonium carbamate is produced by reacting ammonia and carbon dioxide at high pressures (up to 200 bar) in a special reactor.The urea reactor is a reactor vessel inside a protective shell. Abstract: This invention provides a dispensing assembly which is adapted to deliver two separate instantaneously coreactive liquid streams into an external contacting zone. compounds in the laboratory. It is also used in the manufacturing of pyrimidines. It acts as an ammoniating agent. It is used for the denitrification of exhaust emission and as decomposition stabilizer. United States Patent 4420635 . (i) reaction between liquid ammonia and carbon dioxide gas to form ammonium carbamate: 2NH 3 + CO 2 ↔ NH 4 COONH 2 The corrosion problem rests with one chemical produced by the urea process, ammonium carbamate. The ‘Hazard classification and labelling’ section shows the hazards of a substance through a standardised system of statements and pictograms, as has been established under CLP (Classification Labelling and Packaging) Regulation. Author: James Gremillion One of the key problems urea plants face is corrosion. Ammonium carbamate is an important intermediate for the production of urea. Various commercial urea manufacturing processes today use this base case process i.e. It plays a crucial role in the development of carbamoyl phosphate, which is fundamental for pyrimidines and urea cycle production. BASF offers crystal ammonium carbamate that always meets highest standards regarding quality and purity. Ammonium carbamate is used in the production of carbamoyl phosphate, an important ingredient in urea cycle, where it is used as intermediate. In addition to this, it is used in the preparation of trimethylsilyl carbamate. NH2CONHCONH2 + NH3 biuret This reaction is undesirable, not only because it lowers the yield of urea, but because biuret burns the leaves of plants. Ammonium carbamate is used in the preparation of fertilizers. It plays an important role in the formation of carbamoyl phosphate, which is essential for urea cycle and pyrimidines production. NH2CONH2 + H2O urea The urea manufacturing process, shown schematically in Figure 2, is designed to maximise these reactions while inhibiting biuret formation: 2NH2CONH2! ammonium carbamate NH2COONH4!
