Urea → Cyanuric acid

Participants

Reaction Steps

The solution of urea and/or biuret in the inert organic solvent is circulated at high velocity through the recycle loop and is maintained at a temperature of not less than 180° C. or higher thereby forming a solution or slurry of cyanuric acid in the inert organic solvent. The crystallizer heretofore mentioned is maintained at subatmospheric pressure and the solution or slurry is introduced therein in a manner as to maximize agitation of the solution or slurry of cyanuric acid.
