Process for preparing cyanuric acid |
摘要 |
An improved process for the preparation of cyanuric acid in which urea/biuret is converted into cyanuric acid but wherein the co-production of the impurities, ammelide and ammeline is significantly reduced. Cyanuric acid is prepared by heating urea/biuret in a suitable polar organic solvent in the presence of an ammonium-, alkali metal- or alkaline-earth metal nitrate.
