Abstract
The process of the invention is directed to an improvement in purifying cyanuric acid which contains as a contaminant, an enclosed residue of a solvent used in the reaction mediums to produce cyanuric acid from urea, biuret or mixtures thereof. The process comprises suspending the impure cyanuric acid in an aqueous medium and stirring. As a result of the process, cyanuric acid is substantially freed from enclosed residues of contaminants solvents.
