Procedure

To prepare the solution, water was placed within a container and then agitated while dicyandiamide was added. The phosphoric acid was subsequently added. The resulting mixture was heated to approximately 85° centigrade and held at that temperature for approximately 45 minutes. The mixture was then cooled to approximately 25° centigrade and urea was then added. The resultant solution is hereinafter denoted as solution 6 and produced guanyl urea phosphate and urea.
