実験手順

Steam was applied to the jacket, the agitator was actuated at low speed, and the mixture was heated to 135° C. The isocyanuric acid was solubulized by the caustic soda into a thin opaque fluid. While maintaining agitation and a temperature of 135° C., melamine powder amounting to 22 pounds, having a mean particle size of 25 microns, was added through the top addition port. The opaque fluid became very white in color and thickened as the chemical reaction to form the very insoluble melamine cyanurate adduct took place. The agitation was continued at 135° C. until the reaction was completed and the product adduct was evenly distributed throughout the thick fluid.
