USES 1. Melamine production:
4
Melamine set of 6 full plate (09 yellow) List Price:Rs.999 Selling Price : Rs.449 You Save Rs. 550 (55% Discount)
5
Ingredient in : – Resins, plastics, adhesives, coatings, textile anti- shrink agents and ion exchange resins.

Problems in the reactions 1. unconverted NH 3, CO 2 and Ammonium carbamate must be recovered and reused. This is troublesome 2.formation of dimer(urea): must be <1% as it adversely affects plants growth. 3. carbamate decomposition is : SLOW ENDOTHERMIC 4. CARBAMATE is: highly corrosive to ordinary & stainless steels But in presence of Oxygen, 300 series steels can be used. Hence air is intentionally added along with raw materials into the reactor.
