For most applications, ammonium carbamate substitutes ammonia. 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 NH2CONHCONH2 + NH3 biuret This reaction is undesirable, not only because it lowers the yield of urea, but because biuret burns the leaves of plants. compounds in the laboratory. ammonium carbamate NH2COONH4! 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. BASF offers crystal ammonium carbamate that always meets highest standards regarding quality and purity. Various commercial urea manufacturing processes today use this base case process i.e. It is used for the denitrification of exhaust emission and as decomposition stabilizer. ammonium carbamate are as an ammoniating agent and as an intermediate in the production of urea, a component of chemical fertilizers. It acts as an ammoniating agent. 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 is used in the preparation of fertilizers. In addition, ammonium carbamate is also used in pesticides and fumigants to control rodents and insects. It plays a crucial role in the development of carbamoyl phosphate, which is fundamental for pyrimidines and urea cycle production. Commercial production of urea was started in Germany by I.C Farben in 1920 based on ammonium Carbamate process. It plays an important role in the formation of carbamoyl phosphate, which is essential for urea cycle and pyrimidines production. Ammonium carbamate is used in the production of carbamoyl phosphate, an important ingredient in urea cycle, where it is used as intermediate. Ammonium carbamate is an important intermediate for the production of urea. (i) reaction between liquid ammonia and carbon dioxide gas to form ammonium carbamate: 2NH 3 + CO 2 ↔ NH 4 COONH 2 Author: James Gremillion One of the key problems urea plants face is corrosion. Hazard classification and labelling. The corrosion problem rests with one chemical produced by the urea process, ammonium carbamate.

United States Patent 4420635 . It is also used in the manufacturing of pyrimidines. 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. In addition to this, it is used in the preparation of trimethylsilyl carbamate. Ammonium carbamate production . More Information; Description: Beilstein Number: 3914091 Uses: Ammonium carbamate is used in the production of fertilizers by acting as an ammoniating agent.
