Abstract
A process is described for the purification and recovery of cyanuric acid from a hot slurry of cyanuric acid in an organic solvent. In the process, the hot slurry is quenched in a quench liquid which is at a temperature for cooling the hot slurry to form a cooled slurry of cyanuric acid particles in a mixture of the solvent and the quench liquid. Cyanuric acid particles are separated from the mixture of solvent and quench liquid and recovered. The process effectively cools and separates cyanuric acid from the solvent and any color bodies present to produce a pure white crystalline product.
