Triuret is an organic compound with the formula 2NH It is a product from the pyrolysis of urea. Triuret is a colorless, crystalline, hygroscopic solid, slightly soluble in cold water or ether, and more soluble in hot water.
Synthesis
It is prepared by heating thin layers of urea, the thin layers facilitating escape of ammonia:
- 3 2NH + 2 NH3
It can also prepared by treatment of urea with phosgene:
- 2 2NH + 2 HCl
Triuret is a complicating by-product in the industrial synthesis of melamine from urea.
