Abstract: A process for the production of cyanuric acid in which urea and an inert solvent are passed into a reaction zone in which pyrolysis of the urea with the formation of cyanuric acid takes place at 200 DEG to 300 DEG C, from 50 to 760 mm and a space-time yield of from 0.1 to 2 kg of cyanuric acid per liter of reaction volume per hour, and the cyanuric acid is separated in a crystal separation zone and freed from solvent in a falling film evaporator.
