Procedure

A paddle mixer with built-in blade mill was used to mix 50 kg deionized water, 80 kg lead oxide (PbO) and 31.1 kg cyanuric acid. The mixture was heated to between 140° and 150° C., with the consequent rise in pressure to between 5 and 6 bar. The reaction was complete after one hour. The lead cyanurate formed was then dried in the same apparatus at 40 mbar to a residual moisture of less than 1%. 108.1 kg neutral lead cyanurate Pb3 (C3N3O3)2.2H2O was obtained.
