Abstract
Cyanuric acid is prepared by heating urea in the presence of sulphuric acid. 100 mols. urea are mixed with 1-15 mols. sulphuric acid and the mixture heated at 120-140 DEG C. under normal pressure while stirring. The resulting semi-solid mass is heated at 180-200 DEG C. and extracted with boiling water to remove ammo nium sulphate and leave a residue of cyanuric acid. Specifications 416,599, 443,119 and 570,715 are referred to.
